Default Astron Power Supply problem

2 470uf in parallel is close to 1000uf. This was on the Extra class
Ham exam.


Wow - I don't remember anything that basic when I took my Extra.

Default Astron Power Supply problem

What makes you think that a janitor, who happens to be employed at a
university, would know the difference between series and parallel
capacitors?

Gary, I was not commenting on the OP's statement, but the responders
question about capacitors in "SERIES".... If you will notice, in the
header of his responce, he is posting from ksu.edu which is a university.
Therefor he is either a Student, Professor, or Staff at that institution,
and should have known better, than to post such a STUPID Reply.

enough to them to post such a meaningless reply.....

Well, perhaps because they enjoy trolling?

Mcalhoun must have been thinking about resistors!

Nope. Was thinking (if that word even applies here) about combining
capacitors to reach a desired working voltage instead of capacitance !-(


....[snip]....
and they didn't have any 1000uf but they did have some 470uf caps so I
put two of them in parallel to get close to see if it mattered....
^^^^^^^^
I sure hope you meant "series"!-)

Why?


The only alibi I can give is "a senior moment".

But WOW! Umpteen follow-on responses discussing janitors, etc.!
(Now I understand why the information-transfer rate
on this newsgroup sometimes seems pretty low!)
