Electrostatic Shielding :
It is the process of isolating a certain region of space from external field.
It is based on the fact that electric field inside a conductor is zero.
Electrostatic Induction :
Electrostatic induction is a method to create or generate static electricity in a material by bringing an electrically charged object near it. This causes the electrical charges to be redistributed in the material, resulting in one side having an excess of either positive (+) or negative (−) charges.
It is possible to obtain charges without any contact with another charge.
They are known as induced charges and the phenomenon of producing induced charges is known as electrostatic induction.
It is used in electrostatics machines such as Van de Graaff generator and capacitors.
Capacitance of a conductor :
The capacitance of a conductor is defined as the ration of the charge given to the conductor to the potential developed in the conductor.
