Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...
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 ...
As electronics applications continue to become more compact, powerful, and versatile, the final system demands and complexities of mobile and stationary devices also are becoming increasingly ...
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 ...
There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...
A sanitary wiring job takes a little effort and patience, but the result is worth the effort! For some strange reason, many rodders exhibit a great deal of resistance when it comes to dealing with ...
Understanding welding current and learning how a welding circuit interfaces with a building’s electrical system prevents horror stories from happening and leads to correct diagnosis when an incident ...
Unfortunately, making the proper choices when sizing electrical conductors can get complicated. For one thing, the ampacity tables can be very confusing — especially if you don’t understand the “why” ...
