AC Voltage across diode waveform

Click For Summary
SUMMARY

The waveform of AC voltage across a diode exhibits distinct characteristics based on the diode's biasing. When the diode is forward biased, the voltage drop is approximately 0.7V, while in reverse bias, the full AC voltage is present. The circuit configuration consists of an AC generator connected in series with a resistor and a forward biased diode. This setup effectively demonstrates the behavior of diodes in AC circuits.

PREREQUISITES
  • Understanding of diode operation and characteristics

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
