ELECTROSTATIC POTENTIAL AND CAPACITANCE. 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 constant of proportionality is known as the capacitance of the capacitor. Capacitance is the ratio of the change in the electric charge of a system to the corresponding change in its electric potential. The capacitance of any capacitor can be either fixed or variable, depending on its usage.
