These relays work by using an … WebMar 16, 2024 · An electrical relay is an electromechanical device that is used to switch electrical circuits on and off. These relays work by using an electromagnetic coil to generate a magnetic field, which pulls or releases a spring-loaded contact. When the coil is energized, the contact is closed, and when it is de-energized, the contact opens. WebIn common with all electromechanical relays, a power relay uses a small electrical current (typically tens of milliamps) to operate the contacts of an electromechanical switch that control a much larger current. For a power relay, this current is usually more than 10 Amps which makes the devices suitable for applications with higher currents.. Finder’s current … siddharth public school delhi
