Photodiode Working Principle

A photodiode is a semiconductor device that converts light into current. The current is generated when photons are absorbed in

Over Heat Of Resistor Resistors are probably the most robust of all electronic components, with high reliability and a long

reverse-biased varactor diode

Varactor Diode Operation

The junction capacitance of diodes varies with the amount of reverse bias. Varactor diodes are specially designed to take advantage of

Zener Diode Limiter Working

Zener Diode Limiter

Zener diodes can be used in ac applications to limit voltage swings to desired levels. Below Figures shows three basic ways
