Homework Statement
The e.m.f of a battery is 12V and provides an electrical energy of 500J. What is the amount of charges flowing in the battery for 5 seconds?
2. The attempt at a solution
Since V=W/Q, rearranging the equation gives you Q=W/V:
Q= 500/12 = 41.6666667 C
But, I don't know what is the 5 seconds for. So, I just put 41.6666667 C as the answer and I got it wrong.
