Electricity is a common term used to define the flow of charged particles. The rate of flow of charge is called electrical current and in some definitions the rate of flow of current is called electricity. At atomic level we have some atoms in which we have electrons and protons. The electrons are bound to their nuclei through electrostatic forces, if a higher potential difference is applied then it will try to pull the electrons out of their normal trajectories, and once the electrons are able to overcome the electrostatic force of nucleus they will flow out of their atoms and will move freely.
The rate of flow these fee electrons, is called electric current. Off course this flow of electrons depends a lot on the total potential difference applied across the material higher the difference of electric potential is higher are the chances that the electrons will flow out of their atoms. Electricity is the greatest invention of this age due to this today many things are possible, it provides us light making several things visible.
It is due to electricity that today many important things, like medical operations, production, construction etc are as possible without sunlight as they are during the day. Other than being a source of light and visibility it is a source of power to drive industries and many house hold things as well.
