A particular 12 V car battery can send a total charge of 100 A-h (ampere-hours) through a circuit, from one terminal to the other. (a) How many coulombs of charge does this represent? (b) If this entire charge undergoes a change in electric potential 12 V, how much energy is involved?A particular 12 V car battery can send a total charge of 100 A-h (ampere-hours) through a circuit, from one te?a) 100J/s-h = 100C/s*3600s/h = 360000C
b) V = E/q so E = V*q = 12*3.6x10^5 = 4.32x10^6J
