if it takes 82J to move a certain amount of charge through an electrical device whose potential difference is 0.29 volts.
A) how much work is done?
B) how many coulombs of charge was moved?
a) work done = change in potential energy
= 82 J
b) work done = q*V
where q = charge
V = potential difference
82 = q*0.29
q = 282.75 C
so the charge moved was 282.75 C

A particular 3 volt battery can send a total charge of 96 amp-hours through a circuit from one terminal to the other. (Because 1 amp = 1 C/s, an amp-hour is a measure of charge.) How many coulombs of charge does this represent? If this entire charge "falls" through a potential difference of 3 volts, how much energy is involved? (That is, enter the *magnitude* only...)
