Question

state the kind of energy transformation that takes place in the following devices

1 electric heater
2 electric motor
3 steam engine
4 microphone
5 hydroelectric power station
6 solarbattery

Answer 1

1. Electric to Heat.
2. electric to mechanical.
3. Heat to mechanical
4. sound to electric to sound.
5. heat to electric
6. Light to why electric

Answer 2

We know that we cannot produce or destroy energy,we can just change the form of the energy.

Similarly;

1) Electric heater converts the electrical energy into heat energy.

2)Electric motor converts the electrical energy into kinetic energy.

3)Steam engine converts the heat energy into kinetic energy.

4) Microphone converts sound energy into electrical energy.

5) Hydroelectric power station converts the kinetic energy into electrical energy.

6)Solar battery converts the solar energy to electrical energy.
