Diodes are semiconductor devices that play a fundamental role in electronics by allowing the flow of electrical current in one direction while blocking it in the opposite direction. They are used for rectification, signal clipping, voltage regulation, signal demodulation, and many other applications. To understand diodes thoroughly, follow these steps:
Basic Diode Operation:
Begin by understanding the basic operation of a diode. Diodes have two terminals: an anode (positive) and a cathode (negative). Current flows easily from anode to cathode when the diode is forward-biased, but it is blocked in reverse bias. Diode Symbol:
