Relays are electronic devices that allow for the control of one electrical circuit by another electrical circuit. They work by using an electromagnet to switch a circuit on or off. The basic components of a relay include a coil, contacts, and a yoke.
The coil is made up of copper wire that is wound around a core. When a current flows through the coil, it creates a magnetic field that attracts the yoke. The yoke is a piece of iron that is attracted to the magnetic field created by the coil.
The contacts are the parts of the relay that open and close to allow or prevent the flow of electricity through the circuit. When the yoke is attracted to the magnetic field created by the coil, it moves the contacts to the closed position. When the current flowing through the coil is turned off, the magnetic field disappears and the yoke returns to its original position, opening the contacts and stopping the flow of electricity.

Relays are commonly used in a variety of applications, such as in automobiles, industrial control systems, and home appliances. They are often used in situations where high voltages or currents are involved, as they can provide isolation between circuits and protect delicate electronic components.
In conclusion, relays are essential components in many electrical systems. They allow for the control of one circuit by another, providing safety and efficiency in a wide range of applications.
