Does any body have an idea what kind of wattage this resistor can take? the wire appears to be about 16 gauge(the wire has a diameter of 1.01 mm according to my dial vernier) and has a resistance of 11 ohms. I don't know the length of the wire.
that fits great with my estimated 33.9 -39.9 milliohms of resistance per an inch.18 awg nichrome is .422 ohms per foot, which translates to .035 ohms per inch.
So, it is quite likely 18 awg nichrome. I agree with cork_ie that it is part of a heating element that has been cut down for some special purpose - maybe a dummy load for something, or maybe a heating element for some specific voltage. Ohms law will tell you how much current it will conduct at various voltages.that fits great with my estimated wire length and estimated 33.9 -39.9 milliohms of resistance per an inch.
indeed, when trying to find the resistance for the gauge wire I have, I found a nice table with the gauges and amperage for different temperatures. I have learned much about heating elements. however I doubt I'll be using this thing for a heater any time soon, I'll use it as a dummy load in my higher power circuits.You've probably realized that nichrome comes in different diameters for different purposes. In my clothes dryer, there are 2 diameters, one for 1800 watts and one for 5000 watts. I'm sure there are several more sizes.
I got it along with several other things from a friend who was into electronics. He recommended using it as a dummy load and said to just move the end ring if I needed lower ohms of resistance(ie. that is to say less turns of the wire.)So, it is quite likely 18 awg nichrome. I agree with cork_ie that it is part of a heating element that has been cut down for some special purpose - maybe a dummy load for something, or maybe a heating element for some specific voltage.
