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: ...

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.

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...
