SPH4U - Nov. 17, 2014 Electric Charge, Coulomb’s Law, Electric Fields

Prerequisite Knowledge

Law of Conservation of Charge

◦ Charge can be transferred from one

object to another, but the total charge of a

closed system remains constant.

Coulomb – the SI unit of electric charge, C

Prerequisite Knowledge

Conductor – any substance in which

electrons are able to move easily from

one atom to another

Insulator – any substance in which

electrons are not free to move easily

from one atom to another
