ELECTRICAL AND ELECTRONICS ENGINEERING LABORATORY To Verify KCL (0-200) mA (0-200) mA 1 k (0-30) V 2.2 k A A I I2  1.5 k rps dc  I1 A (0-200) mA PROCEDURE: 1. To verify KVL:  Connect the circuit diagram as shown in figure[1]  Switch ON the supply to RPS.  Apply the voltage (say 5v) and note the voltmeter readings  gradually increase the supply voltage in steps  note the readings of voltmeters  sum up the voltmeter readings(voltage drops) , that should be equal to applied voltage(e.m.f)  Thus KVL is Verified practically 2. To verify KCL:  Connect the circuit diagram as shown in figure[2]  Switch ON the supply to RPS.  Apply the voltage (say 5v) and note the Ammeter readings  gradually increase the supply voltage in steps  note the readings of Ammeters  sum up the Ammeter readings(I1 and I2) , that should be equal to total current(I)  Thus KCL is Verified practically 4
