D) rectifier

Question

Quizplus · Accepted Answer

A thyristor, also known as a silicon controlled rectifier (SCR), is a type of semiconductor device that uses internal feedback to produce switching action. It is commonly used in power control applications to regulate the flow of current to a load. Thyristors can be turned on and off by applying a small current to the gate terminal, and once turned on, they will remain conducting until the current flowing through them drops below a certain level. This makes them ideal for applications such as motor control, lighting, and heating. Transistors, zener diodes, and rectifiers do not exhibit internal feedback and do not produce switching action.
