It came up at the help desk
, but I want to put this before diyaudio.com members generally:
I feel strongly that people who build audio equipment as a hobby should take it upon themselves to obtain a basic understanding of both the practical and theoretical aspects of electronics. Take a trip to the library and read through the first couple of chapters of electronics textbooks, that kind of thing.
It's more than just the safety aspect, I think of it as a basic necessity...
So, how many people here are familiar with the following statement?
The impedance of a capacitor is -j/([omega]C)
Familiar as dirt? Never heard of it before?
