Hope this is right Factor of ten would make you a scientist. Factor of two would make you an engineer. Factor of 50 or more makes you wrong, usually... <g> 33 AWG wire (.007 in, 0.18 mm diameter) would be about one ohm for five feet. The fuse will have more resistance than the whole rest of the wire, quite likely. :) david
