How does a Diode work ?

 

he first experimented with letting the current flow in only one direction was in 1874. It was to a German physicist, Karl Ferdinand Braun, that we owe this first experiment with a galena crystal. Galena is a mineral largely composed of sulfur. Galena-based diodes were then used to rectify the alternating current and turn it into direct current.

A diode is an electrical device. It is a polarized dipole. This means that it has a connection direction with a positive terminal and a negative terminal.

The purpose of a diode is to only let current flow in one direction. It can also be part of the rectifiers whose role is to transform the alternating current into current with only one direction which one will call unidirectional.

Diodes have numerous applications across the electronic industry, and they are an integral part of any electronic device. In this video, we will explore the inner workings and applications of the diode in great detail. Apart from the basic working of the diode, this video also explains V-I characteristics and applications of diode (rectification using Bridge rectifier) with help of animation.
