Question

the potential difference between 2 points in a current carrying conductor when 1 joule of work is done to move a change of 1 coulomb from one point to the other a)1 ampere b)1 volt c)1 newton d)1ohm

Answer 1

hey mate here is your answer..
it's b. 1 volt

Answer 2

b)1 volt is the correct answer.

We can find the changes between A and B points due to current flow between these two points.

But it is not mandatory to know the exact potential at each point such as A and B.

But you can identify the potential difference between two points, A and B and this potential difference is measured by volt (V).
