Kirchhoff's Law

Daw Moe Sandar Aung Associate Professor Natural Science Department University of Computer Studies, Yangon.

OBJECTIVE To apply Kirchhoff's rules for circuits to a two loop circuit in order to determine the currents and voltage drops in each loop..

APPARATUS Resistors, DC power supply (or) 9V battery, connecting wires, digital multimeter and breadboard..

. . . Kirchhoff's Current Law (KCL) states that at any junction of a circuit, the sum of all the currents entering the junction equals the sum of the currents leaving the junction . In other words, electric charge is conserved..
