Difference between Series and Parallel Circuits

Difference between Series and Parallel Circuits

There are two main types of circuits: series and parallel. In a series circuit, the current flows through each component in sequence. In a parallel circuit, the current divides and flows through multiple components at the same time. In this post, we’ll take a closer look at the difference between series and parallel circuits. We’ll also discuss some of the benefits of using each type of circuit. By understanding these concepts, you’ll be able to choose the right circuit for your project. Let’s get started!

What is Series Circuit?

Series Circuit is an electric circuit in which there is only one path for the current to flow. The current flows through all the components of the circuit in a single loop. Series circuits are often found in household electrical systems, where they are used to connect outlets and light fixtures to the main power supply. Series circuits are also used in many electronic devices, such as radios and televisions. One advantage of series circuits is that they are very simple to design and build. However, one disadvantage is that if one component in the circuit fails, the entire circuit will stop working. Series circuits are also susceptible to voltage drop, which can reduce the overall performance of the circuit.

What is Parallel Circuit?

A parallel circuit is a closed circuit in which the current paths branch off and combine again. The main feature of a parallel circuit is that each individual branch has the same voltage as the source. The amount of current flowing through each branch can be different, and the total resistance of the circuit is equal to the sum of the resistances of the individual branches. One advantage of a parallel circuit is that if one branch is broken or otherwise disconnected, the current can still flow through the other branches. Another advantage is that increasing the number of branches in a parallel circuit reduces the overall resistance of the circuit. This can be useful when trying to increase the current flowing through a given load. The main disadvantage of a parallel circuit is that if one branch shorts out, it can cause all of the other loads to stop working as well. This is why most household circuits are wired in series parallel rather than purely parallel configuration. In this way, if one light bulb burns out or one appliance trips its circuit breaker, other lights, and appliances on the same circuit will still work.

Difference between Series and Parallel Circuits

Series and parallel circuits are two different types of electrical circuits. Series circuits are also called linear or resistive circuits because they have only one path for the current to flow. This means that if one light bulb in the circuit burns out, the entire circuit will be broken. In contrast, parallel circuits have multiple paths for the current to flow. This means that if one light bulb in the circuit burns out, the rest of the bulbs will stay lit. Both types of circuits have their own advantages and disadvantages. Series circuits are simple and easy to design, but they are less efficient than parallel circuits. Parallel circuits are more complex and require more planning, but they are more efficient because each component in the circuit is doing its own job.


Although both series and parallel circuits have their benefits, it is important to know the difference between them before you decide which one to use for your project. By understanding how each circuit works and what its advantages are, you can make an informed decision about which type of circuit will best suit your needs.
