Silicon Controlled Rectifier (SCR)

A Silicon Controlled Rectifier (SCR) is a semiconductor device used to control power flow in electrical circuits. It acts like an electronic switch that can turn on when triggered by a small electrical signal and remains on until the current stops or drops below a certain level. Think of it as a gate that stays open once opened, allowing large amounts of electricity to pass through. SCRs are commonly used in power regulation, motor control, and industrial equipment because they efficiently manage high voltages and currents with precise control.
