Relays are fundamental components in electrical circuits, used to control the flow of current based on an input signal. The construction of a relay typically involves an electromagnet, contacts, and an armature. When an electric current flows through the coil of the electromagnet, it generates a … Read More


Relays are electromechanical instruments that utilize an electromagnet to switch an electrical circuit. The basic structure of a relay comprises a coil, armature, contacts, and a spring mechanism. When current flows through the coil, it creates a magnetic field which attracts the armature, causin… Read More
