Dear amarnath

The potential difference between any two points A and B in an ΔV =V_B -V_A
electric field is defined as the change in potential energy of the system divided by
the test charge q_o :

ΔV=ΔU /q_o = -_A∫^B E.ds

Potential difference should not be confused with difference in potential energy.
The potential difference is proportional to the change in potential energy, and we
see from Equation that the two are related by ΔV=ΔU /q_o
