    Hi Petrucciowns,

    The average load voltage divided by the load resistance will give you the average load current which is the average diode current.

    Thanks for the reply,

    Hm, I know that is how to find the peak diode current, but the average diode current is different. How is the average diode current found? I tried to see if it was the same value in RMS but that is not correct. So I'm stumped.

    To find a average voltage, you have to finding the area under the output curve over a full cycle (2∏)
    So you need to calculate the definite integral from 0 to ∏, to find area under the curve.
    And then:
    Vavg=area/2∏=1/2∏*∫Vpsinθ dθ =Vp/∏
