Question
What is electrostatic shielding? How is this property used in actual practice? Is the potential in the cavity of a charged conductor zero?
✓

Answer

The field inside a conductor is zero. Sensitive instruments are shielded from outside electrical influences by enclosing them in a hollow conductor. Potential inside the cavity is not zero/potential is constant.
