thyristor

A thyristor is a type of electronic switch used to control the flow of electrical power in circuits. It acts like a gate that can turn on or off the current passing through it. Once turned on with a small trigger signal, it remains on and allows electricity to flow until the power is turned off or the circuit is reset. Thyristors are commonly used in power regulation, motor control, and light dimming because they efficiently handle high voltages and currents, making them essential components in managing electrical energy in various industrial and electronic applications.
