which one carbon fiber/kevlar is a better non conductor, as i have read many site and they dont relly tell you the non conducting qualities of each materials, many thanks.

We are taught that with alternating current electricity supplies the current (i.e. electrons) move foreward and then backwards with each cycle.  If the wire to my computer delivers 100 volts and 1 amp at 60Hz, how far are the electrons moving back and forth in the wire 60 times per second - namometers, centimeters?
