# Resistance in series and parallel

## 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.

## Chilled practice question

Calculate the current in a circuit if it is supplied with a voltage of 36v and has two resistors in series on 6 ohms and the other 3 ohms

## Frozen practice question

Three resistors are connected in parallel, resistor a is 2 Ω , resistor b is 5 Ω, and resistor c is 7 Ω . In relation to the other resistors what would the total magnitude of the resistance be ?

## Science in context
