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 ...

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

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: ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create a ...

Fuses are essential parts of power-distribution systems because they prevent fire or damage to electronic equipment. Fuses have the disadvantage of requiring replacement after every burnout, but they ...
