The diagram shows a battery made from three $1.5\,\text{V}$ cells. What is one advantage of arranging the cells like this?
- AThe battery can supply a current for a longer time than a single $1.5\,\text{V}$ cell.
- BThe battery can supply any e.m.f. between $0\,\text{V}$ and $4.5\,\text{V}$.
- CThe battery supplies more energy to each coulomb of charge than a single $1.5\,\text{V}$ cell.
- DThe e.m.f. of the battery is $4.5\,\text{V}$.
