Electromotive force and potential difference — practice question

The quantities X and Y are measured in the same unit, Z. X is the energy dissipated by a battery when it drives unit charge around the whole circuit. Y is the work done in a component when it drives unit charge through the component. What are X, Y and Z?

  • AX: electromotive force, Y: potential difference, Z: coulomb
  • BX: electromotive force, Y: potential difference, Z: volt
  • CX: potential difference, Y: electromotive force, Z: coulomb
  • DX: potential difference, Y: electromotive force, Z: volt
