If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

This video provides a clear explanation of inductors and their role in electronic circuits. Inductors are passive components ...

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 ...

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.

Electronics-loving orthodontic clinician Dr. Mark Brickley has developed a collection of electronic circuit-building experiments, tested them on unsuspecting colleagues, and then squeezed them into a ...

Electrical circuits might be regarded as rather mundane pieces of classical engineering. But their electromagnetic fields are, like light, a quantum object whose energy comes in discrete units — ...
