This video explains what a diode is and how it controls the direction of current in electronic circuits. Diodes allow current to flow in only one direction, making them essential for rectification, ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

Frederik Dostal explains the rise of the ideal diode and how it can be used to develop more robust power systems.

The circuit was designed to provide a means for measuring the operating voltage of zener diodes before applying on a circuit. Zener Diode – a special kind of diode that permits the flow of current in ...

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 ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
