Definition of Diode working and application

The definition of diode is very simple, “A diode is a two-terminal polarized electronic component which mainly conducts current in one direction and blocks in other direction. Its resistance in one direction is low (ideally zero) and high (ideally infinite) resistance in the other direction.” There are various types of Diode like Zener, Schottky, tunnel, […]
