Diodes Explained – Diode – Working principle PN junction | forward and reverse biasing | IV curve

A diode is a two-terminal electronic component that conducts current primarily in one direction , it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices.
