Homework Help: E&M Question

  1. Feb 20, 2005 #1
    Hi all,
    I need to find the current through a resistor knowing the # of electrons passing through it over a given time, t. Can someone help me out with this?
    I thought it was just I = #elec/time, but this cannot be right (i'm getting values along the lines of 1.5E19 Amps)

    Thanks,
    Brad

    1 Amp = 1 Coulomb/Sec
    {Electron Charge} = 1.602x10^(-19) Coulombs
