Objective: To verify that in a closed electrical circuit the algebraic sum of the emfs and the voltage drop in the resistances is equal to zero
Equipment Required
Circuit Diagram
Procedure
1. Connect the circuit as per the circuit
diagram
2. Switch on the power supplies (10 V and 5 v)
and note down the readings in the ammeter and voltmeters.
3. Calculate the IR drop across each resistor.
4. Verify V1 + (-V2) = IR1
+ IR2 + IR3
