Static Electricity

1. Electric Field

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

1.2. The direction of the electric field lines give the direction of the force acting on a positive test charge.

2. Laws of Electrostatics

2.1. Positive & Negatively charged

2.2. SI Unit of electric charge is coulomb (C)

2.3. Like charges repel; unlike charges attract

3. Principles of Electrostatics

3.1. Charging is done by transferring charges from one object to another. it is generally due to the movement of electrons.

3.2. Induction is the production of electric charge on the surface of a conductor under the influence of an electrostatic field.
