1. The problem statement, all variables and given/known data
A 1.5-volt, AAA cell supplies 750 milliamperes
of current through a flashlight bulb for 5.0 minutes,
while a 1.5-volt, C cell supplies 750 milliamperes
of current through the same flashlight
bulb for 20. minutes. Compared to the total
charge transferred by the AAA cell through the
bulb, the total charge transferred by the C cell
through the bulb is
(1) half as great (3) the same
(2) twice as great (4) four times as great

2. Relevant equations
W= VIt

3. The attempt at a solution
Actually am not absolutely sure which formilar to use.. if I try using the one I provided above then my answer will turn out '3'... bu am still not sure!! i Need assistance!

Re: Electricity

The definition of current is $$I=\frac{dQ}{dt}$$. What is a formilar?
