D)J/C

Question

Quizplus · Accepted Answer

The volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Using the formula for power (P = IV) and rearranging it to solve for V, we get V = P/I. Since power is measured in Joules and current is measured in Coulombs per second (or Amperes), we have the units V = J/C, which is option D.
