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: ...

Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

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.
