    It asks for a number of Volts. What entity is measured in Volts? What entity is measured in Watts?
    How did you get your answer?

    Then you are misinterpreting them. Please see my edited post #3.

    As I said, post #3 in the thread. I edited while you were replying to it the first time, so you may have missed the extra questions.

    Volts is measured in joules per Coulomb

    No, Volts are measured in Volts. But that is not what I asked. What physical property do Volts measure? What physical property do Watts measure?

    Volts is the electric potential while Watts is rate of energy

    Right. So if it asks for a number of Volts then an answer in Watts cannot right, can it.
