    Hi I have this lab about exploring rectifier diode and zener diode.
    I have this question I have problem to answer.

    "You measured the current through the diode (rectifier diode) and voltage accross the diode using the multimeter in the lab.
    Use a point in the reverse bias region and the forward bias region, make a reasonable estimate of the resistance of the meter, and compensate the effect of the meter. In what situation would you expect that this meter induced error would be largest?

    Please can someone help me about this question please?
    I dont see how to do it.

    Thank you

    In one case, no current flows through the diode. So the meter resistance would make a parallel path.
