Potential Difference
The electric
potential difference (V) is the work
done per unit charge as a charge is moved
be- tween two points in an electric field
The conditions specified above
are called the standard conditions and the
EMF so obtained is the standard
reduction potential
Electromotive force, the difference in
charge is stored as electrical potential
energy is known as
emf. It is
emf that causes a current to flow in
ac.
