10/6/2011 Physics for Scientists & Engineers 2 2 Complex Circuits In each circuit, which resistors are in series and parallel? Some circuits can be constructed that cannot be resolved into series or parallel systems of capacitors or resistors
10/6/2011 Physics for Scientists & Engineers 2 3 Kirchhoff’s Rules To handle these types of circuits, we must apply Kirchhoff’s Rules. Kirchhoff’s Rules can be stated as Kirchhoff’s Junction Rule The sum of the currents entering a junction must equal the sum of the currents leaving a junction Kirchhoff’s Loop Rule The sum of voltage drops around a complete circuit loop must sum to zero
