Examples of Energy Transformation

Here are some examples of energy transformations taking place in our daily life

Electric Motors

This is used in different appliances like fans, refrigerators etc

Here Electrical energy is converted into Kinetic Energy

Electrical Energy → Kinetic Enrgy

Electric Generator

It is used to generate electricity

Here, Mechanical Energy is converted into electrical energy

Mechanical Energy → Electrical Energy

Electric iron

It is used to iron clothes.

Here, electrical is converted into heat energy.

Electrical energy → Heat energy


Electric Bulb

It is used to produce light.

Here, electrical energy is converted into heat energy which is then converted into light energy.

Electrical energy → Heat energy → Light energy

In case of a CFL, the electrical energy is directly converted into light energy and hence there is no wastage of energy. Therefore,

CFLs are preferred.

Radio

It is used to listen to songs or news.

Here, electrical energy is converted into kinetic energy which is then converted into sound energy.

Electrical energy → Kinetic energy → Sound energy

Steam Engine

It is used to run trains.

Here, heat energy is converted into kinetic energy.

Heat energy → Kinetic energy

Car engine

It used used to run cars

Here, chemical energy is converted into heat energy which is then converted into kinetic energy.

Chemcal energy → Heat energy → Kinetic energy
