How relays work😲:
*Relay:*
A relay is an electromechanical switch consisting of an electromagnetic coil and one or more sets of contacts. When an electrical current flows through the coil, it generates a magnetic field, causing the contacts to open or close.
Relays act as remote-controlled switches, allowing low-power circuits to control high-power devices.
Application:
Relays are extensively used for electrical isolation and to control high-power circuits with low-power signals.
They find applications in automation, power distribution, and electronic systems where the separation of control and load circuits is crucial.
Relays are essential in scenarios where a small control signal needs to manage a larger electrical load.
