## Resistor Divider Formula

The following formula is used to calculate the output voltage of a circuit with two resistors.

Vo= Vs * R2 / (R1 + R2)

- Where Vo is the output voltage
- Vs is the voltage source
- R1 and R2 are the resistances of the resistors.

## Resistor Divider Definition

A resistor divider is a type of circuit with two resistors that changes the output voltage of a given source voltage. It’s main use is to reduce voltage output.
