Physics (AS & A Level) · Oct / Nov 2016 · Paper 12 · Question 36

Four statements about either potential difference or electromotive force are listed. 1 It involves changing electrical energy into other forms. 2 It involves changing other energy forms into electrical energy. 3 It is the energy per unit charge to move charge around a complete circuit. 4 It is the work done per unit charge by the charge moving from one point to another. Which statements apply to potential difference and which apply to electromotive force?

1. Apotential difference: 1 and 3; electromotive force: 2 and 4
2. Bpotential difference: 1 and 4; electromotive force: 2 and 3
3. Cpotential difference: 2 and 3; electromotive force: 1 and 4
4. Dpotential difference: 2 and 4; electromotive force: 1 and 3
