    A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. The heart of a relay is an electromagnet (a coil of wire that becomes a temporary magnet when electricity flows through it).
    Posted by Jenn Braza | DIY Electronics | 1 A relay is an electromagnetic switch that opens and closes circuits electromechanically or electronically. A relatively small electric current that can turn on or off a much larger electric current operates a relay.

    What is a relay and how it works?

    Working

    • Relay works on the principle of electromagnetic induction.
    • When the electromagnet is applied with some current it induces a magnetic field around it.
    • Above image shows working of the relay .A switch is used to apply DC current to the load.
    • In the relay Copper coil and the iron core acts as electromagnet.

      A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.

      Relays are electric switches that use electromagnetism to convert small electrical stimuli into larger currents. These conversions occur when electrical inputs activate electromagnets to either form or break existing circuits. By leveraging weak inputs to power stronger currents, relays effectively act as either a switch o…
