Electric Potential Energy and Electric Potential
What is it?
Electric potential energy is the energy associated with the position of a charge in an electric field. Electric potential at a point is electric potential energy per unit positive test charge: V = Uq
In simple words
- Potential tells electric potential energy per unit charge.
Recommended for Class 12
Full school-level explanation
Electric potential energy is the energy associated with the position of a charge in an electric field. Electric potential at a point is electric potential energy per unit positive test charge: V = Uq
Potential vs Potential Energy
When a charge is placed in an electric field, its position can be associated with potential energy. If a charge `q` has electric potential energy `U` at a point: V = Uq Therefore: U = qV Electric potential is a scalar quantity. Its SI unit is: volt (V) and: 1 V = 1 J/C Potential `V` describes the electric field location itself. Potential energy `U` also depends on the charge placed there. Therefore two different charges placed at the same point experience the same electric potential but can have different electric potential energies.
Reference Level
Potential is measured relative to a chosen reference. For isolated point charges, zero potential is commonly taken at infinity.
Formula / Key Relation
**V = Uq** **U = qV** **1 V = 1 J/C**
Remember
- V = Uq
- U = qV
- 1 V = 1 J/C
