This video explains the function of inductors and how they store energy in a magnetic field when current flows through them. Inductors are essential passive components used to manage current changes ...

This video explains the role of resistors in electronic circuits and how Ohm’s Law defines the relationship between voltage, ...

Churning with voltage and resembling an explosion at the wire factory, the breaker panel exudes mystique. But it's just a big switch, filled with other smaller ­switches, which lead to the switches ...

The difference between static discharge and continuous current is explained. Introduction to Electric Current: The difference between static discharge and continuous current is explained. Sources of ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.
