Electrostatic study of stationary electric charges
Electrodynamics charges in motion
Example of a common insulator rubber
Electric charge is a property of ? matter
What are electrical charges measured coulombs
in?
5 General Laws of Electrostatics 1. like charges repel and unlike charges attract
2.the electrostatic force between two charges is
directly proportional to the product of their
quantities and inversely proportional to the square
of the distance between them
-higher charges=greater force
-inverse square law
3. electric charges reside only on the external
surface of conductors
4. the concentration of charges on a curved surface
of a conductor is greatest where the curvature is
greatest
5. only negative charges are free to move in solid
conductors
-positive charges do not move
