VERIFICATION OF KIRCHOFF’S VOLTAGE LAW
NAME : Purva Sharma
REG. NO. : 21BCE0169
LAB SLOT : L5+L6
DATE : 20.9.2021
Aim: To verify the Kirchoff’s Voltage Law
Procedure:
1. Connections are made as per the circuit diagram.
2. Change the component and source value according to the give circuit.
3. Create new simulation profile and set analysis type as bias point.
4. Run the simulation and note down the readings in tabulation.
5. The voltages V1, V2 and V3 across each resistance is measured for different values of input voltage V.
6. Add the voltages V1, V2 and V3.
7. Compare the simulated results with solved values.
8. Observe that the algebraic sum of voltages in a closed loop is zero.
9. Verify KVL for the loop present in the given network.
Theory:
Kirchhoff’s Voltage law states that the algebraic sum of the voltage around any closed path
in a given circuit is always zero.
In any circuit, voltage drops across the resistors always have polarities opposite to the
source polarity. When the current passes through the resistor, there is a loss in energy and
therefore a voltage drop. In any element, the current flows from a higher potential to lower
potential. Consider the fig (1a) shown above in which there are 3 resistors are in series.
According to Kirchoff’s voltage law…. V = V1 + V2 + V3
Analysis:
