@jippie For ferrite core inductors I have a little tool. I enter the material, size, desired inductance, and then it outputs me the windings. I do them and usually they are at most 5% off... (whatever of that is to be attributed to my meter). However when I look at datasheets of similar ones I find +-10 or even 20% tolerance...
@Gowtham Even with the not-so-great conductive ground we have, we can use it as a conductor. For example, some power systems use the actual ground as the return conductor, instead of cabling a neutral wire.
Even though soil is not a great conductor, the possible cross-sectional area is very very large.
I'm a bit confused about the concept of ground, and perhaps voltage as well, particularly when trying to analyze a circuit. When I learned about Ohm's law in grade school, I learned how to apply the law to calculate current, voltage, and resistance of simple circuits.
For instance, if we were g...
@KyranF I don't know which would be worse...working at 600 kV myself (and trusting that everything everybody else set up was done right)... or designing equipment for that work and sending somebody else out with his life depending on my work.
@PlasmaHH Also remember that they are probably trying to set a loose spec to minimize the need for testing. Like if you order 5% resistors, they will usually all be within 1% of nominal. If they are "6-sigma" they will be setting specs at at a point where yield loss is 1 in a million. And most of the actual parts will be much closer to nominal.
@ThePhoton I understand that very well for all kinds of other devices, but for inductors it should depend mostly on number of windings (which is dead easy to control) and A_L ... unless of course A_L is hard to control, but then I must have been lucky to get A_L values very near to the specified values
I think it's possible that when we see a shit question, we all click on it and start commenting/posting crude answers, which actually makes the question look "interesting" and "hot" when it's really a bad example of a good question. That's the nature of EE.SE these days, and while it's funny (for us) it looks bad from outsiders perspective. There's been a lot of discussion about this general negative attitude on the EE.SE Meta of course
This happens moreso than a genuinely good question popping up, thanks to the flood of terrible quality questions we get here daily
yeah, it seems that it drags people to the specific sites that then start asking worse questions, which get on hot, and then there are slightly worse questions that get hot too etc. in a downwards spiral..
I can see that in waves on aviation I think
But the flood of terribly bad questions isn't as bad as on SO ;)
This one ended up on the hot list because of all the comments under it. But most of the comments were non-technical meta. I have edited the question to make it more on-topic. Still, there are 3x close votes.
@PlasmaHH Yes, that's a softie question. But, part of the answer is: "You may or may not be able to accomplish that in software, you may need a hardware solution". It took us a week to get enough clarifications from the O.P.
@NickAlexeev something that shouldnt be necessary... putting things on hold should at least set some incentives to add useful information ;) in the question though he asks for a fix to the code... sure for many such processing adding some hardware can be a solution but I think not many people would have thought he wants something besides a fix to his code...
@KyranF what I really hate is people whining about that a downvote is not explained.
@NickAlexeev hehe, ok. reading around on meta, it seems that there isn't much of clear guidelines on when/what to migrate... I don't want to sound rude/offensive, but.. maybe the mods should have a (chat) meeting or so? I dont care much, but I flagged that question, migration request was declined, asking another mod (you) it gets migrated... everyone is different but I see how some people may find it quite arbitrary (there was one recent meta post about that too)
being part of a C++ irc channel I really love strict topics and sending people to the right place btw...
