Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

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: ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
