Charge:
Electrons are negatively charged particles and they transfer energy through wires as electricity.Charge is a property of a body which experiences a force in an electric field. Charge is measured in coulombs (C).Since electrons are so small and one electron will not have much of an effect anywhere, it is more useful to refer to packages of electrons. One coulomb of charge is a package equivalent to 6,250,000,000,000,000,000 electrons
