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 simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

Transient cosmic ray phenomena produced by a solar superstorm can be linked to variations in atmospheric electricity.

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.

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 ...

Schneider Electric’s 800VDC sidecar not only aligns with emerging standards from Nvidia, it supports Google, Meta, and others ...

Researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. They used a probe originally developed to measure the electrochemical signal ...
