# Voltage Divider Calculator

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.

#### Formula:

V_{out} = [ R_{b} / (R_{a}+R_{b}) ] x V_{in}
**where,**
V_{in} = Input Voltage
V_{out} = 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
