Electrostatics properties of a conductor:
When placed in electrostatic field, the conductors shows the following properties:
Ne
Frictional electricity : The electricity developed by rubbing or friction is called frictional electricity. The rubbed substa
Electric potential: The electric potential at a point in an electric field is the amount of work done in moving charge from infinity to that point.
Charge --Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
Two kinds of charges : The following simple experiment proves these facts:
Rub a gla

Dimensions of a Physical Quantity.
The powers to which fundamental quantities must be raised in order to express the given physical quantity are called its dimensions.
To make it more clear, consider the physical quantity force
Dielectric:
A dielectric is a substance which does not allow the flow of charges though it but permits them to exert electrostatics forces on one
