# Voltage Divider Calculator English Español

Voltage divider rule refers to the partitioning of a voltage among the components of the divider. A voltage / potential divider is a simple linear circuit that produces an output voltage (Vout) that is a fraction of its input voltage (Vin) mainly used in physics. Generally, Vout is used as a reference voltage. Use this online voltage divider calculator to find the reference voltage. Enter the input values in the potential divider calculator to find the Vout value.

Generally, Vout is used as a reference voltage. Use this online voltage divider calculator to find the reference voltage. Enter the input values in the potential divider calculator to find the Vout value.

#### Formula:

Vout = [ Rb / (Ra+Rb) ] x Vin where, Vin = Input Voltage Vout = Output / Reference Voltage Ra, Rb = Resistances

### Example:

A series circuit has three resistors with both resistors having resistance of 5 and 8 ohms and the input voltage of 2 volts. Find the reference voltage applying the potential divider / voltage divider rule.

#### Solution:

Vout = [8 / (5+8)] x 2
= 1.23 volts
