Voltage Divider Calculator

See our other Electronics Calculators.

One of the most basic and common circuits is the two resistor voltage divider. The ratio of the resistors divides and input voltage down to a lower voltage. This calculator simplifies the task.

Voltage Divider Circuit Schematic
Inputs:
Input Voltage: (V)
Results:
Output Voltage:
(V)
Ratio (R1/R2):
Fill in one of the parameters below and the other two will be computed.
R1 (KOhms)
R2 (KOhms)
R1+R2 (KOhms)

See our standard resistor calculator for a real world resistor value.

Equations:

Vo= Vin*R2/(R1+R2)

R2/R1= Vo/(Vin-Vo)
