The previous tutorials featured resistors in direct current (DC) circuits wherein the voltage and current have been assumed to be of constant polarity, flow and direction. The voltage, current and ...

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.

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: ...
