KIRCHOFF LAW

KIRCHOFF CURRENT LAW (KCL)


A node with four connected branches



 I1 + I2 = I3 + I4
I1 + I2 - I3 - I4 = 0
Total current = 0
Total Current Out = Total Current In

KIRCHOFF VOLTAGE LAW (KVL)


Definition: Kirchhoff’s Current Law states that the algebraic sum of currents entering a node is  zero. The sum of the currents entering a node is equal to the sum of the currents leaving a node.
