Resistor Divider Calculator

Enter the source voltage and resistances of two resistors into the calculator. The calculator will evaluate and display the voltage output of the circuit.

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.

Resistor Divider Example
