Electrostatic Potential – Class 12 | Chapter – 2 | Physics Short Notes Series PDF for NEET & JEE
Electrostatic Potential: It is a term used in physics to describe the amount of electrical potential energy that is stored in a system of charged particles due to their distribution and arrangement. It is a scalar quantity that is proportional to the amount of work required to move a unit positive charge from a reference point to the location of the charged system. The electrostatic potential at a point in space is defined as the amount of work required to move a unit positive charge from an arbitrarily chosen reference point to that point, with the electric field being zero at the reference point.
Units of Electrostatic Potential
- SI unit: volt
- Other units: statvolt
- Symbol: V or φ
- Dimensional Formula: ML2T3I-1
Formula of Electrostatic Potential
The formula also known as electric potential, at a point in space is given by:
V = W/q
where V is the electrostatic potential (in volts), W is the work done in moving a positive charge q (in coulombs) from the reference point to the point in question, and q is the charge of the particle being moved.
