2. Lecture 2 Summary: Electric Charge CHARGE is a basic attribute, like mass + - and - + attracts -- repels ++ MATTER is normally electrically neutral Unit: 1 Coulomb = 6.25 x 10 18 basic charges e = 1.6 x 10 -19 Coulombs Charge is QUANTIZED Protons: charge +e, heavy Electrons: charge –e, light Conductors: charge free to move Insulators: charge positions fixed - + - -
