# Difference Between Series and Parallel Circuits

All electric devices need circuits to run smoothly and efficiently. An electric circuit consists of many instruments attached to it such as resistors, diodes and switches which are positioned in a circuit structurally. And with these structure of placement, there is a difference in output. The placement of components in the wrong area or even in the wrong terminal creates a lot of issues. Hence, it is important to understand the basics of circuits thoroughly to master the trade.

Individual resistors are either connected in a series connection or a parallel connection or sometimes both series and parallel to produce a more complex resistive network whose equivalent resistance is the mathematical combination of the individual resistors connected together. In the next few sections, let us learn about the different types of circuit connections and their differences and similarities.

## What is a Series Circuit?

A circuit is said to be connected in series when the same current flows through all the components in the circuit. In such circuits, the current has only one path. Let us consider the household decorative string lights as an example of a series circuit. This is nothing but a series of multiple tiny bulbs connected in series. If one bulb fuses, all the bulbs in series do not light up.

## What is a Parallel Circuit?

A circuit is said to be parallel when the electric current has multiple paths to flow through. The components that are a part of the parallel circuits will have a constant voltage across all ends.

## Difference Between Series and Parallel Circuits

The major difference is that the series circuits have the same amount of current flow through all the components placed in it. It got its name due to the fact that components are placed in the same single path of the flow of current in the electric circuit. On the other hand, in parallel circuits, the components are placed in parallel with each other. This circuit splits the current flow. The current flowing from the source will be divided into the current flowing through each of these components.

Difference Between Series and Parallel Circuits
Series Parallel
The same amount of current flows through all the components The current flowing through each components combines to form the current flow through the source.
In an electrical circuit, components are arranged in a line In an electrical circuit, components are arranged parallel with each other
When resistors are put in a circuit, the voltage across each resistor is different even though the current flow is the same through all of them. When resistors are put in this circuit, the voltage across each of the resistors is the same. And even the polarities are the same
If one component breaks down, the whole circuit will burn out. Other components will function even if one component breaks down, each has its own independent circuit
If $V_{t}$ it total voltage then it is equal to V1+V2+V3 If $V_{t}$ it total voltage then it is equal to V1=V2=V3
