EXPERIMENTAL VERIFICATION OF KIRCHHOFF’S VOLTAGE AND CURRENT LAWS

AIM:

To verify (i) Kirchhoff’s current law and (ii) Kirchhoff’s voltage law

KIRCHHOFF’S CURRENT LAW

THEORY:

The law states, “The sum of the currents entering a node is equal to sum of the currents leaving the same node”. Alternatively, the algebraic sum of currents at a node is equal to zero. The term node means a common point where the different elements are connected. Assume negative sign for leaving current and positive sign for entering current.

PROCEDURE:

1. Connect the circuit as per the circuit diagram.

2. Switch on the supply.

3. Set different values of voltages in the RPS.

4. Measure the corresponding values of branch currents I1, I2 and I3.

5. Enter the readings in the tabular column. Find the theoretical values and compare with the practical values

FORMULA:

∑ Currents entering a node = ∑ Currents leaving the node

I1 = I2 + I3
