Across the diode

What is the difference between option D and E and how to determine the choice?

Hint: Look at where the ground is. Positive charges flow to the ground.

Sorry for necroposting, but I am curious about the answer whether is D or E. I didn't get your hint, either. Is it D since it can't get underground?

The current is going clockwise in the circuit so the oscilloscope will read only positive values. So the answer is D.

Thank you. By the way, regarding necroposting, how long is the limit here?

There's a limit?

Well, some forums forbid replying to an old thread with various limits. Some are three months, other two months, and others one month. In MMF it was three months.

NecroPosting

It's rather rare that anyone can be bothered to go through the old posts on this forum.

If it is not a problem (and I have never found it to be one) then there is no need to make a rule against it.

If I worked for a site that had an "age limit" then I would occasionally have to delete old threads. As I have not been told to do that then I must assume there isn't an age limit.

And hey, as long as the costs of keeping the data aren't outrageous some of those old problems are good ones to learn from, too.

Well, I like scavenging old problems in old threads, collecting some interesting problems. However when I myself can't solve it (or can't comprehend the reasoning), what else can I do other than reviving the topic?

Btw topsquark, please help me in my new thread. I am meeting a dead-end there (or rather more precisely, can't even open a path).
