Hmmm. My American Electricians Handbook shows the DC resistance of
14AWG stranded copper wire to be .002624 ohm per foot.


5 feet would be .01312 ohm. (I imagine there's more than 5 feet...)


At 10 amps, the voltage drop is 0.1312 volts.


What meter do you have that won't measure 1/10 of a volt accurately?


Did you get it at Harbor Freight?
