The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

Understanding the role of short-circuit current is critical to the reliability of your electrical system and to the safety of the people who maintain it. When designing or modifying a 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 ...

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.

Current regulators (non-switchable and switchable) are a new family of useful and versatile devices targeted for use in communications, networking and power conversion circuits. Current regulators (or ...

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.

CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage, ...

Flow of electric charge is known as electric current and in electric circuits the charge is carried by moving electrons in a wire. In this article you will get 10 solved Physics practice questions ...
