Hello! I was reading up on carbon composition resistors, to see whether they're as good as audiophiles would claim. According to this page http://www.geofex.com/article_folders/carbon_comp/carboncomp.htm, high voltages are needed before harmonic distortion is noticeable. Could I therefore connect audio to a step-up transformer, put a carbon comp in series, and use a transformer with the same ratio (but as a step-down) after the resistor and achieve suitable distortion?
PS. a transformer increases V or I while decreasing I or V in proportion. Is that right??
----
One of my tutors said that the voltage drops in a series resonant circuit are higher than the supply voltage. How is this possible if a capacitor and inductor are passive components? I read that at f.res the 'impedances cancel out'. How is it possible for series resistances to cancel out?
I've included a li'l circuit, you can use it to explain this.
thanks!
