1 Definition

Electricity: It's the science that studies the movement of the electrons.

 The electrons have energy. Electricity is a form of energy that moves quickly. It's a very useful way to transport energy far from its origin. (From power station to the city).

                Electronic: It's a branch of technology that studies the uses of electricity to transmit information.

Electrical circuit: It’s the path where the electrons move to change the kind of energy.

Current: is the movement of electrons along a conductor. The electrons jump from one atom to another. When there are more atoms moving the current is more intense.

Electric tension difference

Electric tension is the difference in electrical potential between two points
