    Hello, I had a diode and a resistor connected to the oscilloscope where the 10k resistor was after the diode. The Source was 10Vpp 1kHz and when I connected it the wave I got is attached. Why does the wave come out like that?

    I havent learned about rectifiers yet since my lab class is before my lecture(I know its stupid) but from the link I'm guessing the circuit is only showing the ac signal? Uhh is this a half wave rectifier? Since theres the time gap where the signal goes down.

    Are you familiar with the operation of the diode?

    Yes, this is a half wave rectifier, which lets only the positive voltage go through it. Any negative voltage will be dropped on the diode an will show up on the oscilloscope, just as the experiment proves.
