RE: Any scope photos of different resistors...

Posted by rick_m on December 26, 2014 at 07:45:15:
Well, I don't have any pictures for but have experienced all sorts of resistor issues over the decades. Mostly the issue is excess noise but microphonics happen also. Carbon composition resistors are the worst things going because they are both noisy and microphonic. Metal films are usually the best. One way to think about carbon resistors is to consider telephone "transmitters": the thing you speak into. Essentually the active piece is a carbon resistor.

Maybe your friend should read a little rather than just looking at the pictures?
