Suppose the battery on your phone delivers a current of 0.740 mA (that's milliAmperes) over a time of 4.00 hours. What is the total charge that flows out of the battery during this time?

AND

How many electrons flow out of the battery during this time?

I=q/t =>
q=It=0.74•10⁻³•4•3600=10.66 C,
N=q/e=10.66/1.6•10⁻¹⁹=6.66•10¹⁹
