SUMMARY
The energy stored in a fully charged battery with a constant voltage of 4V and a capacity of 2 A-h is calculated to be 28,800 Joules. This is derived using the conversion of ampere-hours to coulombs, where 2 A-h equals 7,200 C. The formula used is Joules = Voltage * Coulombs, leading to the calculation of 4V * 7,200C = 28,800 J. The solution is confirmed to be correct.
