Introduction to Electricity Symbol: (q) Unit:Coulomb (C) The fundamental electric quantity is charge. Atoms are composed of charge carrying particles: electronsand protons, and neutral particles, neutrons. The smallest amount of charge that exists is carried by an electron and a proton. Charge in an electron:qe= C Charge in a proton:qp= CChargeCurrent Current moves through a circuit element through variable. Current is rate of flow of negatively-charged particles, called electrons, through a predetermined cross-sectional area in a conductor.
