The diagram illustrates a circuit. Which statement about the circuit is incorrect?
- AElectromotive force is the energy transferred per unit charge.
- BEnergy is transferred from chemical potential energy in the cell to other forms when the switch is closed.
- CThe electromotive force of the cell is greater than the terminal potential difference when the switch is closed.
- DWhen the switch is open, the voltmeter measures the electromotive force of the cell.
