This video explains how resistors function and how Ohm’s Law defines the relationship between voltage, current, and resistance in electronic circuits. Resistors are passive components used to control ...

IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature are particularly severe, and tend to limit the range over which these devices can operate. The d.c.

It’s no secret that I’m a sucker for photography — I’ve been known to take a photo or two in my time — and I have a hell of a weak spot for electronics, to boot. In the upcoming Open Circuits from No ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...
