Homework Statement



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.

Homework Equations



A-h=3600 C
1 Joule= V*C.

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 ?
