Electric field and Electrostatic Potential Energy.

Description
Definition of electrostatic potential energy along with conservative force has been calculated.Potential for a number of charge for example a pair of positive charges and a pair of charges with opposite polarity is calculated.The difference between potential and potential energy and flow of positive charges from higher potential to lower potential is explained. An experiment is performed with Van-de Graaff generator and florescent tube showing a large potential difference in a strong electric field.
