## What is Resistance in series and parallel?

Resistors in series and in parallel change the total resistance in a circuit. Special components called resistors are made especially for creating a precise quantity of resistance in a circuit. They are generally made of metal wire or carbon and constructed to maintain a stable steady amount of resistance over a wide range of environmental conditions.

## Resistance in series and parallel equation

To calculate Resistance in series and parallel we write the equation like this.

$R_t = {\mathit R_1 \text + \mathit R_2}$

## Resistance in series and parallel demo

In this tutorial you will learn how to calculate total resistance of resistors in series and parallel.
