Do you know about relay

Question

Accepted Answer

A relay is an electrically operated switch that uses an electromagnet to control the flow of current in a circuit.

Relays are commonly used in electrical systems to control high-power devices with low-power signals.
They can be used to switch on/off motors, lights, and other electrical components.
Relays have an input coil that generates a magnetic field when current flows through it, causing the switch contacts to open or close.
They provide isolation between the control circuit and the controlled circuit, protecting sensitive electronics.
Relays can be categorized into different types such as electromagnetic relays, solid-state relays, thermal relays, etc.
