In this topic, you study the Series and Parallel combination of resistances with neat sketch.
In this combination, the resistances are connected in series and in parallel as shown in Fig. 1.
Fig. 1. Series-parallel circuit
This circuit is solved Step by Step, first the parallel branches, as shown in above figure, are solved, then the parallel circuits are resolved into the equivalent series resistances and finally the series circuit into the equivalent circuit. Thus the total resistance and current drawn are calculated.
