2. - - + Lecture 2 Summary: Electric Charge + - +
CHARGE is a basic attribute, like mass + -
and - +
attracts
repels
Unit: 1 Coulomb = 6.25 x 1018 basic charges
e = 1.6 x Coulombs
Charge is QUANTIZED
MATTER is normally electrically neutral - +
Protons: charge +e, heavy
Electrons: charge –e, light
Conductors: charge free to move
Insulators: charge positions fixed
