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 ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

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.

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

What is resistance? The most common definition of resistance is the opposition to current flow—more specifically the flow of electric charge in a material. The circuit element used to model this ...

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...
