2.1 INTRODUCTION In Chapters 6 and 8 (Class XI), the notion of potential energy was introduced. When an external force does work in taking a body from a point to another against a force like spring force or gravitational force, that work gets stored as potential energy of the body.

This makes a closed conductor shield the inside from outside electric fields. They are useful in protecting sensitive electronic equipment's from stray fields. This effect was first studied by Michael Faraday, and hence closed conductors are often called Faraday cages. Created by Mahesh Shenoy. Questions.

Electrostatic shielding is a method used in the cables that carry audio signals in order to protect them from external interference, such as an electric field produced by air electricity or electric sparks. Elevators in buildings operate as an electrostatic shield.
