Q2. What is mean by relay and how it operates?
Ans. 
A relay is an electrically operated switch that uses an electromagnet to mechanically operate the switch contacts.
• Relays are used to control high power circuits with a low power signal.

• When the coil of the relay is energized, it creates a magnetic field that causes the switch contacts to close or open.

• Relays are commonly used in automotive applications, industrial controls, and home appliances.

• There are different types...read more
