The diagram depicts a battery linked to two resistors. Independently, four students measure the electromotive force (e.m.f.) of the battery, the current through the resistors, and the potential difference (p.d.) across resistor $R$. The table below presents their results. Which row contains values with the correct units?
- Ae.m.f. $3.0\,\text{A}$, current $0.30\,\text{V}$, p.d. $1.5\,\text{A}$
- Be.m.f. $3.0\,\text{A}$, current $0.30\,\text{A}$, p.d. $1.5\,\text{V}$
- Ce.m.f. $3.0\,\text{V}$, current $0.30\,\text{V}$, p.d. $1.5\,\text{A}$
- De.m.f. $3.0\,\text{V}$, current $0.30\,\text{A}$, p.d. $1.5\,\text{V}$
