What is potential difference , Physics

It is the difference among potential at two points of a conductor.

Please note that by potential(at a point A) ,we actually mean potential difference  among  point A and another point where potential is zero(usually we take this point at infinity or some reference level).

Additionally, potential among two points on a conductor having zero resistance is zero.( from ohms law v=iR=I(0)=0)
