A cell has an electromotive force (e.m.f.) of $1.5\,\text{V}$. What is meant by this statement?
- AThe cell converts $1.0\,\text{J}$ of energy when driving $1.5\,\text{C}$ of charge round a complete circuit.
- BThe cell converts $1.5\,\text{J}$ of energy when driving $1.0\,\text{C}$ of charge round a complete circuit.
- CThe cell converts $1.5\,\text{J}$ of energy per second when driving $1.0\,\text{C}$ of charge round a complete circuit.
- DThe cell converts $1.5\,\text{W}$ of power when driving $1.0\,\text{C}$ of charge round a complete circuit.
