Two circuits, the impedances of which are given by Z1 = 15 + j12 ohms and Z2 = 8 – j5 ohms are connected in parallel. If the potential difference across one of the impedance is 250 + j0 V, calculate: ...

Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.
