Electrostatics Flashcards
1
Q
Law of conservation of charge
A
*
The total electric charge of an isolated system remains constant
2
Q
Conductor
A
Material through which electric charge flows freely
3
Q
Insulator
A
Material through which electric charge does NOT flow freely
3
Q
Coulombs Law
A
*
The electric force between two points charges is directly proportional to the product of the two charges and inverserly proportional to square of the distance between them, and directed along the line joining the two charges
F=K q1q2/r^2
4
Q
Electric Field Strength
A
*
(E)
Electric force per positive unit test charge
E=F/q
4
Q
Radial Field
A
Field that extends radially (like electric field around a point charge of the gravitational field around a planet)
