Colombs,Amps,Volts,and Watts. HELP!!!! 1. The problem statement, all variables and given/known data A given car battery is rated at 250 amp-hours. Does this rating indicate the amount of energy, power, charge, voltage, or current that can be drawn from the battery? Explain. 2. Relevant equations Coulombs, Amps, Volts, Watts. 3. The attempt at a solution I first calculated the coulombs that this battery produces in one hour. That turned out to be 250amp-hours X 3600seconds= 900,000. Is this the furthest that I can get?? I am really stumped because I thought I could get more than just the number of coulombs. I tried finding out how many electrons pass through (2.25x10^22) but it seems like I cannot learn joules or voltage by knowing how many total electrons a battery is capable of dispensing. I guess my problem is that I am equating the total number of electrons as a sort of total amount of energy. This is wrong?
