Any circuit composed solely and with more than one path via which current can flow is referred to as a series of circuits. All of the components of a series circuit are wired together so that, in the event of a fault, current cannot flow through the circuit. In a series circuit, the circuit’s overall current is constant. Contrarily, a circuit containing more than one path through which an electricity travels is referred to as a parallel circuit. The current in the parallel circuit is not constant since each component has a different branch for current flow.

What is a series circuit?
When the current flow is constant through all of the circuit’s components, the circuit is said to be in series. The electric current formed in series circuits only travels down one path.
The correlations between current and voltage in a series circuit are exactly the opposite of those in a parallel circuit. Each element in the series receives the same amount of current, which is equal to the source current (Is). In contrast, the impedance (in this case, the resistance) of each series element (V1, V2, V3) affects the voltage across each element. The voltage provided by the source (Vs) is equal to the total of the individual voltage drops across each series element because Kirchhoff’s Voltage Law (KVL) is in effect.
Advantages:
- Simple Design: It has a simple design that is easy to understand.
- Overheating: It does not overheat quickly.
- Higher Output Voltage: It has a higher output voltage so that we can add more power appliances.
- Consistent Current: It carries the same current throughout the circuit.
Disadvantages:
- Increased Components: A circuit’s resistance will increase as the circuit’s overall component count grows. This is a fundamental relationship in electrical circuits, where the presence of more components increases resistance since they pose more barriers to the movement of electrical current.
- Fault Consequences: The entire circuit will be impacted if a fault develops at any point along the circuit. A single flaw might result in a total stoppage in the flow of electricity, which could potentially cause disruptions or damage. Circuit integrity is essential.
What is a parallel circuit?
A circuit containing two or more routes for the current to travel is referred to as a parallel circuit. Each component in a parallel a circuit carries current and is powered by the same voltage.
The voltage across each element in a parallel circuit is the same and equal to the source voltage (Vs), and the current through three resistors in each element (I1, I2, and I3) varies depending on the impedance of each element (in this case, the resistance). According to Kirchhoff’s Current Law (KCL), the sum of the individual currents passing through each parallel element equals the total current coming from the source (Is).
Advantages:
- Component Damage in Parallel Circuits: If one component in a parallel circuit is damaged, the current still flows through the remaining components and doesn’t cease. This means that even if one component is compromised, the others can still work effectively.
- Uniform Voltage in Parallel Circuits: The voltage across each component in a parallel circuit stays constant. As a result of receiving the same electrical potential, all components are guaranteed to operate effectively by the uniform voltage distribution.
- Flexible Component Changes in Parallel Circuits: It is simple to connect or disconnect a new component in a parallel circuit without impacting the functionality of the existing components. Because of its adaptability, the circuit can be easily modified and expanded without affecting the functionality of its present components.
Disadvantages:
- Additional Voltage Source in Parallel Circuits: It is not practicable to use a second voltage source in a parallel circuit. Parallel circuits maintain a constant voltage across components, in contrast to series circuits, which raise voltage by merely connecting batteries in a particular order. The circuit would become more complicated and might not function as intended by adding an additional voltage source.
- Wiring Requirements in Parallel Circuits: Compared to series circuits, parallel circuits often require more wires for connection. Because each component in a parallel circuit is directly connected to the power source, more wiring is required to create these various connections. One of the trade-offs for the benefits of parallel circuits, such as maintaining constant voltage across components, is the additional wiring complexity.
Basic Ideas of Series and Parallel Connection
In order to create such a way a single path for electrons to flow, components in a “series” connection are frequently linked end to end in a line:
On the contrary, the fundamental concept of a “parallel” connection is that all components are linked across each other’s leads. No matter how many components are linked, there can never be more than two sets of electrically common points in parallel configuration in a circuit that is strictly parallel. There are numerous ways for electrons to move, yet there is only one voltage that applies to all parts:
The electrical characteristics of series and parallel resistor arrangements are quite different. In the next sections, we’ll examine each configuration’s characteristics.
Difference between series and parallel circuit
Series Circuit
- A series circuit is advantageous for precise control since the current travels through every component in a single path. It was originally employed, for instance, in home lighting so that one defective bulb wouldn’t influence others. However, introducing more parts raises resistance, and a single malfunction breaks the circuit as a whole. For some applications, understanding series circuits is essential, although they have drawbacks as compared to parallel circuits.
- Any component failure or disconnection in a series circuit destroys the entire circuit, rendering all connected devices inoperative. This can be helpful in some circumstances, such as with holiday lights, where a single problem won’t compromise the entire set-up. However, parallel circuits are more appropriate for applications that call for individual device operation. Effective electrical system design requires an understanding of this distinction.
- All the components are lined up in a single line in a series circuit. This linear arrangement ensures that the current flows through each component sequentially, making it ideal for applications where precise control of electrical devices is necessary.
- Despite the fact that the overall current in a series circuit with numerous resistors is constant, each resistor experiences a variable voltage drop. This occurs as a result of how the resistors’ resistance values are used to split the total voltage among them. This idea is essential when creating circuits with precise voltage control requirements, such voltage dividers.
- V is equivalent to V1+V2+V3 if V is the total voltage across all components in the series circuit.
- R = R1 + R2 + R3 in a series circuit.
Parallel Circuit
- Multiple routes for current flow are provided by a parallel circuit, enabling independent operation of the components. Others continue operating without interruption even if one component malfunctions or is disconnected. Because of this, parallel circuits are perfect for uses like residential outlets that call for the operation of a single device. Additionally, they guarantee constant voltage across all components. In contrast to series circuits, they might be more difficult to design and call for more wiring. Effective design and troubleshooting of electrical systems depend on an understanding of these differences.
- If one component in a parallel circuit is destroyed, the current still flows through the remaining components, assuring the other components’ continued operation. For applications like holiday lights where dependability is crucial, this redundancy is useful. Additionally, parallel circuits keep the voltage constant across each component, guaranteeing uniform performance. Choose carefully based on your demands as they can be more complicated than series circuits due to added wiring.
- All of the parts are arranged in parallel in a parallel circuit, which has several advantages. With a dedicated path to the power supply, each component can operate independently. Others continue to function even if one component fails. To ensure effective functioning, parallel circuits maintain a constant voltage across all components. They also make it simple to add or remove components. Select the design that best fits the requirements of your system because they require more wiring than series circuits.
- In a series circuit with multiple resistors, the current remains constant, but each resistor experiences a different voltage drop. This happens because the voltage is divided among the resistors based on their resistance values. This principle is fundamental in circuit analysis and design, helping engineers ensure each component operates at the right voltage.
- The voltage across each resistor is the same if the resistors are linked in parallel.
- R = 1/R1 + 1/R2 + 1/R3 in a parallel circuit.
Is voltage higher in series or parallel?
Voltage in Series Circuits
A series circuit connects components in a single pathway one after the other. This means that electrons passing through the circuit encounter each component in the order listed. As a result, the voltage across each component accumulates and is divided by the total voltage across all the components connected.
Consider a simple series circuit consisting of two resistors and a battery. Each resistor would see a voltage drop if the battery supplied 12 volts. Let’s say the first resistor drops the voltage by 4 volts, leaving only 8 volts for the second resistor. In a series circuit, the voltage across one resistor in each component is less than the source voltage, and the voltage across the components adds up to equal the source voltage.
Voltage in Parallel Circuits
In a parallel circuit, components are connected across multiple paths, and each component has its own separate branch connected directly to the voltage source. This configuration allows each component in parallel combination to have the same voltage as the source.
Using the same example, if two resistors are connected in parallel to a 12-volt battery, each resistor would experience the full 12 volts. This is because, in purely parallel circuit, the voltage across each component is equal to the source voltage, and they do not share the voltage as in a series circuit.
In summary, the key difference is that in a series circuit, the total voltage is divided among the components, resulting in a lower voltage across each, while in a parallel circuit, each component has the same voltage as the source. This property makes parallel circuits suitable for applications where components need to operate at the full supply voltage independently, while series circuits are used when voltage division among two or more components is desirable.
Why Parallel Circuit is Preferred by Others
- Independent Full Voltage Operation – Each component in a parallel circuit is linked directly to the voltage source through its own branch. This means that each component receives the entire voltage supply. This characteristic is extremely useful in many situations where devices must work independently and at their rated voltage.
- Tolerance for Errors – Parallel circuits provide a substantial advantage in terms of fault tolerance. If one component fails (e.g., a light bulb burns out or a device malfunctions) in a parallel design, the other components remain unaffected and continue to function at full voltage. In contrast, a single component failure in a series circuit might disrupt the entire circuit, causing all connected components to stop working.
- Components can be added or removed as needed – When it comes to adding or removing components, parallel circuits provide more flexibility. You can quickly connect and disconnect devices without interfering with the rest of the circuit’s operation. This is particularly beneficial when you need to expand or adjust your setup without disturbing the entire circuit.
- Voltage Constant Across Components – The voltage remains constant across all components in parallel circuits. This ensures that devices perform reliably and as expected, no matter how many other devices are connected in parallel. This is critical in applications where voltage stability is critical.
- Total Resistance Has Been Reduced – When resistors are connected in parallel, the overall resistance of the circuit is lower than when they are connected in series. In electrical design, this feature is frequently employed to attain specified resistance levels and control current flow.
- In some cases, efficiency has increased – Parallel circuits can be more energy-efficient in cases where components draw varied currents or have different power requirements. When compared to series arrangements in which the same current flows through all components, each component performs at its ideal conditions, potentially saving energy.
In general, parallel circuits are preferred over series circuits in situations where devices must run independently at full voltage, fault tolerance is critical, and component connections must be flexible. Parallel circuits are the favored choice in many practical electrical and electronic applications, ranging from domestic wiring to complicated electrical systems.

However, make sure that you also consider getting help and support from professional electricians like ones from the Arc Angel Electric. We’re sure that they can help you when it comes to your needs and inquiries about electric parts and components.
What is one difference between series and parallel circuits?
One key difference between series and parallel circuits is how the components are connected. In a series circuit, components are connected completely end-to-end, forming a single pathway for current. In a parallel circuit, components are connected across multiple pathways, allowing separate branches for current to flow.
Why use parallel instead of series?
Parallel circuits are preferred over series circuits in situations where you want each component to receive the full supply voltage and where the failure of one component should not affect the operation of others. Parallel circuits are more fault-tolerant and offer greater flexibility when connecting multiple devices.
What is the difference between a series and a parallel circuit?
The primary difference between series and parallel circuits lies in how components are connected and how current flows. In a series circuit, components are connected in a single path, and the same current flows through each component. In a parallel circuit, components are connected across multiple paths, and the total current in only one path is divided among them.
Why is a series circuit better than a parallel?
A series circuit is not necessarily better than a parallel circuit; it depends on the specific application. Series circuits are used when you want to control the current flowing through each component, such as in Christmas lights above circuit top. However, for most applications, parallel circuits are more practical because they offer independent operation of components and are more fault-tolerant.
Is electric current the voltage the same in series or parallel?
Voltage across load components is not the same in series and parallel circuits. In a series circuit, the total voltage is divided among the components, resulting in a lower voltage across each component. In a parallel circuit, the voltage remains the same across all components, matching the source voltage.
Where are parallel circuits used?
Parallel circuits are used in a wide range of applications, including household electrical wiring, electronic devices, power distribution systems, and more. They are particularly useful when you want multiple devices to operate independently and receive the full supply voltage, ensuring that the failure of one component does not disrupt the operation of others.
Summary
It’s always a good idea to know more about certain things if you want to be aware of what you need in the future and this might be the reason why you wanted to know more about circuit components and what they do. To summarize everything, let’s refresh what we have learned about series and parallel circuits.
A series circuit connects components end to end in a single path. This indicates that the same current runs through all components at the same time. Because the voltage is split among several components, the voltage across each one is reduced. Importantly, if one component in a series circuit fails, the entire circuit might be disrupted, causing all connected devices to stop working. Series circuits are commonly employed when controlling the current going through each component, such as in Christmas lights.
Parallel circuits, on the other hand, include connecting components across many channels, each of which is directly connected to the voltage source. This design ensures that each component separately receives the entire supply voltage. Parallel circuits have the substantial advantage of allowing components to operate independently, which means that if one component fails, it does not influence the performance of others. Furthermore, parallel circuits allow for the addition or removal of components without disrupting the entire circuit. They are the recommended option when devices must run independently at their rated voltage.
