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

To calculate the source voltage using the Kirchhoff’s voltage law, add together the voltages of the closed-loop.

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?

1. First, determine the individual voltages.

Measure the individual voltages in each loop.

2. Next, calculate the total voltage.

Sum together each individual voltage to get the total voltage.
