1. VERIFICATION OF KVL & KCL AIM: To verify Kirchhoff’s Voltage Law and Kirchhoff’s Current Law both theoretically and practically. APPARATUS REQUIRED: THEORY: KIRCHOFF’S VOLTAGE LAW: In any closed electrical circuit, the algebraic sum of electromotive forces and the voltage across the impedance is equal to zero.(OR) In a closed circuit, the sum of potential rise is equal to the sum of potential drop. TO DETERMINE THE SIGN OF EMF SOURCE: Potential Rise → Positive Sign TO DETERMINE THE SIGN OF VOLTAGE ACROSS THE IMPEDANCE: Potential Drop → Negative Sign If the loop direction & the current direction are the same then the voltage across the impedance (ie voltage drop) is taken as negative. If the loop direction & the current direction are opposite to each other then the voltage across the impedance (ie voltage drop) is taken as positive. KIRCHOFF’S CURRENT LAW: It states that, the algebraic sum of the currents meeting at a junction or node is equal to zero. (OR) At a junction, the sum of incoming currents is equal to the sum of outgoing currents. In case of AC circuits, the phasor sum of incoming current is equal to the Phasor sum of outgoing currents. Let the currents I1, I2, I3, I4, flow through the conductors meeting at the junction „O‟. Taking currents flowing towards the junction as positive and flowing away from the junction as negative. EXAMPLE: Calculate the current through the each resistor and voltage drop across each resistance of the given network by application of Kirchhoff’s Law. 1
