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
