## Resistance in Series and Parallel

Resistors in series and in parallel can change the total **resistance** in a circuit.

## 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** we use this equation.

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

## Resistance in series and parallel demo

In this tutorial you will learn how to calculate the 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 36 **V** and has two resistors in series one 6 **Ω** and the other 3 **Ω**.

## Frozen practice question

Three resistors are connected in **paralle**l, resistor A is 2 **Ω** , resistor B is 4 **Ω**, and resistor C is 5 **Ω** . What is the total **resistance ** in the circuit ?

## Science in context

**Resistance** in **series** and **parallel** change the total **resistance** in a circuit
