Question

what is the potential difference between two points separated by a l in a conducting wire​

Answer 1

Answer:

The potential difference between two points ΔV is often called the voltage and is given by ΔV=VB−VA=ΔPEq Δ V = V B − V A = Δ PE q . The potential at an infinite distance is often taken to be zero. The case of the electric potential generated by a point charge is important because it is a case that is often encountered.
