Diode wave forms, take a look

[Lucas Organ]

Hey guys and girl, I have made up this little drawing here as I am trying to explain some stuff to a first year apprentice would you mind taking a look and seeing how correct I am. It is some different wave forms for oils cope readings

On the left, I see a correct half-wave and what looks like DC. I have no idea what the right image is supposed to be, nor what you mean by short and open.

A full-wave rectified wave-form should look like the first image, but with additional half-sine-waves between those shown.

Should do a three phase bridge

Lucas Organ:

I think I may have figured out what you are trying to say. But your presentation is somewhat incorrect, incomplete, and shows no circuits to associate with your graphs.

All your graphs are probably displaying time as the horizontal axis with a total time base of about 50 milliseconds. Always label your axis with magnitude and scaling.

I don't know what your vertical axis is. Because your first one is labeled FULL WAVE SHORT I will assume that vertical is current, but that means that somewhere in that series path of the circuit is a voltage source, current limiting resistance, and the diode. Further you are showing a half wave rectifier result, not a full wave rectified output. Further it is important that you define the load on the rectifier. A resistance is the simplest best starting load to show,

You do not know much about circuit theory and should not be teaching a course on this subject.

There is a lot of not so good discussions on the internet for rectifiers, but if you look at a number of these and study them, then you may get a better understanding. You have no business teaching about something that you really do not understand.
