Question

What do we mean by saying that a body has 60 volt electric potential ? Please answer ...?

Answer 1

Consider a charge Q = 1 C. I put this charge in my pocket and I walk from infinity to a point which is at a distance R from the source charge. By the time I reach that point, say I do a work of 60 J. The electric potential( treating infinity to be at zero potential ) is then defined as the ( Work done by me )/Q. It is independent of Q. After calculating, I get V = 60 V. This means that the charge Q is now at an electric potential of 60 V. This configuration( source charge and Q arrangement ) now has the potential to do work.
