A 12 V battery is rated at 200 Ah (Amps hours). How much total energy can it supply?
The Attempt at a Solution
First I did E = 1/2 C V^2. (Got 4,320,000 J, although I'm not sure if that is correct). But now I need to convert it to kwh so my question is can I use P = IV in this manner:
P = 200 Ah * 12 V
P = 2400 Wh = 2.4 kWh
or do I need to manipulate my original energy finding?
4,320,000 J != 2.4 kWh so one must be wrong
