Electrostatic Potential and Capacitance

Edited By Team Careers360 | Updated on May 06, 2022 09:39 AM IST

Introduction:
Chapter 2 electrostatic potential and capacitance Class 12 concentrate on capacitance and electrostatic potential. It's an important first step in understanding the power of energy storage. You will learn the answers to questions that may have been asked in the tests as you progress through the chapter. Apart from being an important chapter in Physics, questions on Electrostatic Potential and Capacitance hold a lot of weight in exams like the Jee and neet. The amount of work done per unit positive test charge, or in moving the unit positive test charge from infinity to that point, against the electrostatic force without acceleration, determines the electrostatic potential at any location in an electric field. Because electrostatic forces are conservative forces, electrostatic potential is a state dependent function.
The amount of work done in transporting a unit positive test charge from one place to the other point against electrostatic force without acceleration is defined as the electrostatic potential difference between two points in an electric field (i.e. the difference of electrostatic potentials of the two points in the electric field). Because the electrostatic field's operation on a test charge in any given charge configuration is independent of the path, the potential difference is the same for every path. When a positive charge is put in an electric field, it is subjected to a force that propels it from higher to lower potential points. A negative charge, on the other hand, is subjected to a force that propels it from a lower to a greater potential.
