Ampere is
the unit used to measure the rate of flow of an electric current.
Electric charge is

Electric circuit is
the path that an electric current follows.
Electric current is
the flow of electric charges.
Electric field is
the influence a charged body has on the space around it that causes other charged bodies in that space to experience electric forces.
Electrode is
a piece of metal or other conductor through which current enters or leaves an electric device.
Electromagnetism is
a basic force in the universe that involves both electricity and magnetism.
Electron is a
subatomic particle with a negative electric charge.
Insulator is
a material that opposes the flow of electric current.
Ion is
an atom or group of atoms that has either gained or lost electrons, and so has an electric charge.
Kilowatt-hour is
the amount of electric energy a 1,000-watt device uses in one hour.
