I'm starting to get into audiotronics and the whole do it yourself thing but I have a question that I haven't found the answer to. Albeit probably a stupid one, but do resistors have a positive or negative side? Thanks in advance!
A fuse is a non linear resistor (when used at currents sufficiently high to cause heating).
Of course the speaker cables (and all others) come into the same catagory when taken to extremes as they are basically the same as fuses except with insulation on them.
Fuses have to be hot in order to work properly; speaker cables don't. That's why speaker cables need to be made of thicker wires for less losses, and have thermal conductive insulation, of minimal thickness for a given voltage and mechanical robustness. I use enamel wires in my walls, like in welding machine transformers. However, for stage systems it is problematic.
