How Is Current Calculated from Electron Flow Rate?

[jbp890]

1. How do you find the current if it tells you how many electrons pass through cross section of a conductor each second



2. ...



3. ...I don't know the first thing to do about this. Just the number of electrons make me think of the equation Q = Ne ..but charge doesn't have to do with anything and current just makes me think of I = Q/t ...not that t has to do with anything either.

Charge has everything to do with it! What is the definition of current? You wrote it yourself, I = Q/t. So the current is the amount of charge passing a point in one second. If you know the number of electrons passing per second, then you know the charge passing per second.
