Law of Conservation of charge
Charge cannot be created / destroyed, only transferred.
Coulomb’s Law
Two point charges exert forces on each other. The force is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
Electrical Field
[Describe]
Region of space in which an electric charge experiences a force. The direction of the electric field at a point is the direction that a positive test charge would move if placed at that point.
Electrical field lines
An imaginary line that indicated the direction & strength along which a positive test charge will move if placed at a specific pt. in the electrical field.
Electric Field at a pt.
Force per unit positive charge.
