Direct Current (DC) — An electric current that flows in only one direction.

Electrolyte — Any substance which, in solution, is dissociated into ions and is thus made capable of conducting an electrical current. The sulfuric acid - water solution in a storage battery is an electrolyte.
Electromotive Force — (EMF) A difference in potential that tends to give rise to an electric current. Measured in volts.
Electron — A tiny particle which rotates around the nucleus of an atom. It has a negative charge of electricity.

Electron theory — The theory which explains the nature of electricity and the exchange of "free" electrons between atoms of a conductor. It is also used as one theory to explain direction of current flow in a circuit.

Farad — A unit of measure for capacitance. One farad is equal to one coulomb per volt.
