Static Electricity

Laws of Electrostatics

2 types of charges

Law of charges

SI unit of charge: Coulomb (C)

Principles of Electrostatics

Charging by Rubbing

The atom that loses an electron is now a positive ion, and the atom that receives an electron is a negative ion.   At no time during this process is charge ever created or destroyed.

Charging by Induction

Induction is the production of electric charge on the surface of a conductor under the influence of an electric field.   The neutral metal spheres will possess equal amounts of opposite charge at the end of the process.   The advantage of charging by inducton is that it can be repeated many times without any loss of charge from the inducing specimen.

Electric Field

An electric field is a region in which an electric charge experiences a force

Electric Field Line

An electric field line is the path a positive charge would take if it is free to move. The direction of the electric field lines gives the direction of the force acting on a positive test charge.
