conversion of energy forms

This device converts electrical energy to sound energy. It is a

• Microphone

• Buzzer

• Solar cell

• Capacitor

Bulb converts

• Electric energy to light energy

• Electric energy to light and heat energy

• Electric energy to solar energy

• Electric energy to heat energy

Mechanical energy is the sum of

• Kinetic energy and potential energy

• Heat energy and light energy

• Light energy and sound energy

• Heat and sound energy

Blackening of Silver Bromide in the presence of Sunlight is the conversion of

• Heat energy into potential energy

• Heat energy into chemical energy.

• Light energy to potential energy

• Light energy to chemical energy

Devices that convert one form of energy into other are called

• Transducers

• Energy converters

• Transistors

• Transformers

When a ball falls towards earth from a height

• Potential energy stored in the ball gets converted to kinetic energy

• Kinetic energy gets converted into potential energy

• PE gets converted to sound energy

• No energy change takes place

When an archer releases an arrow from a bow

• PE gets converted to KE

• Mechanical energy gets converted into KE

• KE gets converted into Heat energy

• No energy change takes place
