The resistance is 69.9 ohms after it cools and with a very tiny current from the ohm meter. I bet it isn't the same at higher temps/currents. As a test, you could run some current through the fuse into a light load (literally a "light" load, as in a light bulb) and measure the current through the circuit and the voltage drop across the fuse. Doing this at a couple different currents (different wattage bulbs) might show the change in resistance with change in current/heating.

I'll bet 10 bucks the resistance will change substantially under different loads. If wrong the 10 bucks will be "donated" to my local tavern tonight after work. If right, one of you guys needs to make the "donation". Any takers? 'hope I'm wrong [Linked Image]
