Description of electric potential difference?

  1. Jul 18, 2015 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    The answer is B, though I thought that electric potential difference is the ratio of energy to charge? Why is the answer stating the ratio of energy to current instead?
