A particular12 V car battery can send a total charge of 84A-h(ampere-hours) through a circuit from one?

terminal to other.(a) How many coulombs of charge does this represent? (b) If this entire charge undergoes a change in electric potential of 12 V , how much energy is involved?A particular12 V car battery can send a total charge of 84A-h(ampere-hours) through a circuit from one?A coulomb is one ampere-second, so 1 A-h is 3600 coul, and 84 A-h = 3.0*10^5 C Energy is potential times charge, so the energy is 36*10^5 J
