Electricity is a form of energy which is formed when electrons flow from one body to the other. An atom is made of electrons, protons and neutrons. The electrons are distributed in shells in the atom of an object. There can be only a restricted number of electrons according to the shell number. If there are fewer electrons in one shell then the electrons from the other body can flow to the object. So we can say the object is negatively charged. This flow of electrons is known as electricity. There are many ways to generate electricity. We can make a normal electric circuit in which the battery can provide electricity (electrons) which will flow through these wires and then light the bulb. .
Static electricity was discovered in the Greece during the 620-550 BCE when a Greek discovered that amber and fur attract each other when rubbed. no one was able to make sense of this discovery for centuries. Slowly the meaning became a little clearer when William Gilbert studied more about the static energy and magnetism. it became more clear only after Benjamin franklins' little experiment with electricity and a kite in which he felt a tingle of electricity pass through him when he touched the metal key attached to the kite during a thunder. Then gradually more people came studied more about electricity and the usage of electricity increased.
Electricity has many efficient uses in our life. It is a form of energy which man has developed to make use of it in modern life. It is used in many electrical appliances in which electrical energy is converted to energy required. For ex - it is used in fan in which electric energy is converted to kinetic energy. Electricity is used to operate the electric motor in a car which is used start the engine. Electricity is used to operate normal lamps and also solar lamps to convert the sight into electricity. Technology and communication amongst people has also improved due to electricity.
