1. The problem statement, all variables and given/known data A battery with constant voltage of 4V and 2 A-h, find the energy (in jouls) stored in the battery when it is fully charged. 2. Relevant equations A-h=3600 C 1 Joule= V*C. 3. The attempt at a solution We have 2A-h=7200 C, and Joules are volt-couloumb, so we multiply to get that the the energy is : 4*2*3600=28800 J. Am I correct ?
