Find Amperage knowing # electrons and time

[Cyrad2]

Hi, I've been having some problems with a homework question. In the problem it tells me the resistance of a resistor, and how many electrons pass through it in a given time. t = 5min. #e = 4.4E21. I need to find V.

So, I need to find I since I know R.

How do I do this? The only formula I could find was I = delta(Q)/delta(t). This gives me a huge value for I along the lines of 1.5E19, which can't be right, can it?

Thanks a bunch,
Brad

Look at the units of Amps.
Coulombs per sec
How many electrons are in a Coulomb?

What's with "1.5E19"...?What does it mean...?
