Q1. What is relay and it's function working
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically control the switching action.
• Relays are used to control high power circuits with low power signals.

• They can be used to control motors, lights, and other electrical devices.

• Relays have an input coil that generates a magnetic field when current flows through it.

• This magnetic field attracts a movable armature, which closes or opens the s...read more
