Why are so many questions getting down voted?
The main reason for many downvoted questions is that the question shows lack of research. For instance, read this page: How do I ask a good question?.
I will make a quotation from that page: -
Have you thoroughly searched for an answer before asking your
question? Sharing your research helps everyone. Tell us what you found
and why it didn’t meet your needs. This demonstrates that you’ve taken
the time to try to help yourself, it saves us from reiterating obvious
answers, and above all, it helps you get a more specific and relevant
answer!
So, if you ask a question that shows no evidence of researching the problem then it can get down-voted quite within reason. In fact, if you hover over the d/v button it says this: -
This question does not show any research effort; it is unclear or not
useful
And my interpretation of that is this: -
- Your question may be downvoted if there is no clear evidence of any research
- Your question may be downvoted if the question is unclear (irrespective of evidence of research)
- Your question may be downvoted if the question is not useful
but many seem to me to be perfectly reasonable questions asked in good
faith.
Please do link to one or two (or several).
Surely if you are going to down vote a question you should at least
give your reasons in the comments (for example "shows no research") so
that the OP can learn and improve their post?
OK that makes sense but, if you hover over the downvote button you get the answer: -
This question does not show any research effort; it is unclear or not
useful
Or maybe you are expecting a deeper analysis of the lack of research to be posted in a comment? If you are then, if this site were not so toxic against someone giving more explicit details then I'd accept your viewpoint.
Just less than an hour ago I got this "dude" arguing with me over what I told him about his question and how it lacked research etc.. I'd like to post that commentary but I flagged it for mod intervention and it's been sent to a black hole. So, sometimes (and probably more often than not) it's just not worth the effort being helpful to someone.
so that the OP can learn and improve their post?
Well, on the many occasions that I leave explicit details of why a question is poor, I get into a word-fight or having to try and justify my downvote. It's just easier for me to give no details and let them figure it out themselves after-all, they can hover over the d/v button.
I don't notice many other folk leaving reasons for downvotes either so maybe they've had the same experience as me?
How does the waveform shown relate to any node on the diagram shown above it?
to which the OP added@Andyaka Hello, so that diagram only shows the controller. I hadn't added the whole circuit diagram as it is fairly standard three phase rectifier but I will add it for clarity
- so he added the details and I removed my close vote. I then tried to extract more info via comments and, by comments this was explained. I don't see what all the fuss is about. \$\endgroup\$
