Kirchhoff's Laws
Although useful to be able to reduce series and parallel resistors in a circuit when they occur, circuits in general are not composed exclusively of such combinations. For such cases there are a powerful set of relations called Kirchhoff's laws which enable one to analyze arbitrary circuits. There are two such laws:
1 st law or the junction rule: for a given junction or node in a circuit, the sum of the currents entering equals the sum of the currents leaving. This law is a statement of charge conservation.
I1 +I2+ I3 = I4 + I5
2 nd law or the loop rule: around any closed loop in a circuit, the sum of the potential differences across all elements is zero. This law is a statement of energy conservation, in that any charge that starts and ends up at the same point with the same velocity must have gained as much energy as it lost.
