electrostatics Strike-through text
it is the branch of science which deals with the study of charge at rest.there are two kind of charges observed in nature 1) positive charge      2) negative charge like charges repel & unlike charges attract each other. in general materials are classified into 3 category 1)conductor=materials which allow electric charge to travel through it easily.                2)insulator=which dont allow electric charge to trvel through it. 3)semi-conductor=materials whose conductivity is in between conductor & insulator.
