A battery is placed in a circuit. It is switched on for $1.0\ \text{minute}$. Over this interval, the current in the circuit is $0.40\ \text{A}$ and the battery transfers a total of $48\ \text{J}$ of energy. Which row shows the charge that passes through the circuit and the electromotive force (e.m.f.) of the battery?
- Acharge that passes in $1.0\ \text{minute}$: $0.40\ \text{C}$; e.m.f. of the battery: $2.0\ \text{V}$
- Bcharge that passes in $1.0\ \text{minute}$: $0.40\ \text{C}$; e.m.f. of the battery: $120\ \text{V}$
- Ccharge that passes in $1.0\ \text{minute}$: $24\ \text{C}$; e.m.f. of the battery: $2.0\ \text{V}$
- Dcharge that passes in $1.0\ \text{minute}$: $24\ \text{C}$; e.m.f. of the battery: $120\ \text{V}$
