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: ...

Alternating current circuits improve the versatility and usefulness of electric power systems. In the late 1800s, Nikola Tesla demonstrated phenomena with alternating current (AC) electricity that ...

In addition, since all waveforms are constant-valued at equilibrium points, and so capacitors act as open circuits and inductors act as short circuits. There in lies the basic algorithm for computing ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...
