Jeez! you're even grumpier than me!
There are definitely people who ask really silly questions & don't pay any attention to your answers,or get aggro when you suggest they do a bit of study!
There isn't a lot we can do about that,except to leave them to stew in their own juice,& not waste any more time on them.
It tends to annoy me,though if people answer some other question,& start rabbiting on with a lot of unrelated
issues,often only half understood by themselves.
Even if you're a grumpy old sod,
your technical answers always make sense.Your grumpy ones are,well,grumpy!
My original comment:"Learn some basic theory--please!"applies to
some of the answerers as well as the questioners.
I don't know if it's just me,but it seems like people shun learning such things as Ohm's & Kirchhoff's Laws,
& fill their heads up with a lot of half understood IEC standards,& stuff like that.
OK, standards are important stuff,but I could teach a Pink & Grey Galah to spout IEC standards whilst hanging
upside down from his perch.
Here in Western Australia,& as far as I know,in the rest of Australia as well,there is a thing called;
"Outcomes Based Education",which seems to be set up,so that if you can perform certain "monkey tricks"
at the end of a course,all is well.Whether you have actually learnt anything apparently doesn't matter!
I've run into people who supposedly have done an "Advanced Certificate",or a "Diploma" in Electronics,to
whom Ohm's Law is a new & startling concept!
