Answer 1

Answer 2

1. Transducers. Traducers are devices that convert one form of energy into another form of energy. e.g. Mechanical energy or temparature change into electrical signals or energy and vice versa.

2.Generators. Devices that use energy and convert it in electrical form are called generators. e.g. When electricity is generated at solar plants or windmills etc.

3.Motors. Devices that use electrical energy to give generally mechanical movements. e.g. A bike, a car

4.Circuits. Circuits consist of minimum three components an energy source( voltage source), a conducting path( wires connected in a loop) and a resistor. Additionally circuits can have capacitors, inductors etc.
