, Electric potential difference
The electric potential difference is defined as the total work done by an external
agent in bringing the unit positive charge from one point to another without
undergoing any acceleration.
Electric potential difference is defined as work done per unit test charge.
Work done in moving a unit positive charge against the electric field from one
point to another is stored as energy which is called electric potential difference.
VA-VB = Wexternal (B→A)/q
=J/C
Potential difference is scalar quantity.
Electric potential
The electric potential is defined as the total work done by an external agent in
bringing a unit positive test charge from infinity to a point against the electric field
without undergoing any acceleration.
Electric potential is defined as work done per unit test charge.
VA-V∞ = Wexternal (∞→A) /q
=J/C
Electric Potential is a scalar quantity.
Work done in moving a unit positive charge against the electric field is stored as
energy which is called electric potential.
