AC Voltage across diode waveform

  1. Feb 6, 2013 #1
    I am wondering how the waveform of AC voltage measured across a diode would look like? What about the waveform of the resistor connected in series with this diode? Please help .

    You need to show a specific circuit, but in general when the diode is forward biased it will have 0 (that's ideal; actual will be ~.7v) and when it's reverse biased it will have the AC voltage.

    The circuit is very simple an AC generator connected to a resistor and a forward biased diode in series. But I see what you mean, I get it now. Thanks
