In this article, we will explore the basic functions of the Zener Diode. This device resembles a compact cylinder, much like the conventional diode, with two terminals at the ends that can be wired or ...

The Zener diode is similar to a general-purpose signal diode which consists of a silicon PN junction. It is a special kind of diode in which current is allowed to flow in the forward direction in the ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...
