what happens to the output graph on a CRO when we replace a PN JN diode in a rectifier with a zener diode?
reply me soon

With just one rectifier diode, you will have the usual half-wave output waveform (positive half-cycle followed by a period of no conduction,then pos. half cycle again followed by no conduction etc.)

IF REPLACED WITH ZENER DIODE: You will have positive half-cycle displayed as well as a part of the negative half cycle, clipped at exactly the zener voltage. Etc., etc.

In addition to the information given by Johann, Volume III - Chapter 3 gives a pretty good explanation of the difference in characteristic when a diode is replaced by a zener diode.
