Enter up to 5 different voltages of a circuit to calculate the total voltage or source voltage.

## Kirchhoff’s Voltage Law Formula

Vs = V1+V2+Vn

- Where Vs is the total voltage or source voltage
- V1, V2, Vn are the voltages in a closed-loop
- n is the number of loops

## Kirchhoff’s Voltage Law Definition

This law states that the sum of all voltages in a closed circuit must equal 0. Therefore, the sum of the voltages across each loop is equal to the total voltage and source voltage.

## Example

How to calculate kirchhoff’s voltage law?

**First, determine the individual voltages.**Measure the individual voltages in each loop.

**Next, calculate the total voltage.**Sum together each individual voltage to get the total voltage.

## FAQ
