Electric generator (dynamo): In electricity generation, a generator is a device that converts mechanical energy to electrical energy. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines and even hand cranks.

An electric motor is nothing but an electro-mechanical device that converts electrical energy to mechanical energy. The very basic principal of functioning of an electrical motor lies on the fact that force is experienced in the direction perpendicular to magnetic field and

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas (plasma). Electric current is measured using a device called an

Nuclear fusion is the process of making a single heavy nucleus (part of an atom) from two lighter nuclei. This process is called a nuclear reaction. It releases a large amount of energy. The nucleus made by fusion is heavier

Nuclear fission is the process in which a large nucleus splits into two smaller stable nuclei with the release of energy. In other words, fission the process in which a nucleus is divided into two or more fragments, and neutrons and energy are released.

A change will occur in the nucleus to make it more stable. The change is called a decay. When a nucleus decays it will emit (give out) some particles or waves. Emitting

Holography is a photographic technique that records the light scattered from an object, and then presents it in a way that appears three-dimensional. Holograms pop up in movies such as “Star Wars” and “Iron Man”. It was also used in

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves of the electromagnetic field, propagating (radiating) through space carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-, and gamma radiation.
