An electric battery’s deliverable charge is measured in ampere-hours. For instance, a battery with capacity $40$ ampere-hours could, if fully charged, provide $0.2\,\text{A}$ for $200$ hours. What is the maximum energy a fully charged $12\,\text{V}$, $40$ ampere-hour battery could supply?
- A$1.7\,\text{kJ}$
- B$29\,\text{kJ}$
- C$1.7\,\text{MJ}$
- D$29\,\text{MJ}$
