3/10/08 Class Notes

Opposite charges attract, while like charges repel.

Objects aquire a static charge by the transfer of electrons

A coulomb is 6.25x10^18 elementary charges

Force obeys inverse square law



Conductors- objects that allow the flow of electricity to go through them



Insulators- objects that stop the flow of electricity from going through them



Conductivity is a continuum


An electric charge creates an electric field
If another charge gets close enough, it will be affected by the field

SI Unit= Newton/Coulomb (N/C)...Equation= E=Fe/q
