9702Practical circuits

The diagram shows a circuit. Which statement about the circuit is not correct?

  1. AElectromotive force is the energy transferred per unit charge.
  2. BEnergy is transferred from chemical potential energy in the cell to other forms when the switch is closed.
  3. CThe electromotive force of the cell is greater than the terminal potential difference when the switch is closed.
  4. DWhen the switch is open, the voltmeter measures the electromotive force of the cell.
