Electromagnetic Relay - How a Relay Works - Electromagnetic Relay Switch • Electromagnetic Relay - How a Relay Works - Electromagnetic Relay Switch • A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. The first relays were used in long-distance telegraph circuits as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. • In this video I will go to show you, How do relay work and their construction? • More videos:- • Resistor │ Resistor color Code│ • • Resistor │ Resistor color Code│ • Resistor| What is a Resistor| Function of Resistor| • • Resistor| What is a Resistor| Functio... • Lightning Arrester - Lightning Arrester Types - Types of Lightning Arresters • • Lightning Arrester - Lightning Arres... • • #electromagnetic_relay • #Relay_Types • #Learning_Engineering • #konok_kamruzzaman • • Follow me on Facebook: / learning.engring • Join on my Facebook group: / 1913745875521183 • • Dear Sir, Thanks for watching my videos.
