Learn A Tungsten Wire Has Resistance R At 20 - Latest Update
See a tungsten wire has resistance r at 20. A given copper wire has a resistance of 510. 28Note -- a few slides earlier wed estimated the typical resistance of a tungsten light bulb filament at 2000C -- that estimate of 70 assumed for simplicity a constant coefficient of resistivity from 20C to 2000C which might not be the. This is a straightforward application of R R 0 1 T since the original resistance of the filament was given to be R 0 0350 and the temperature change is T 2830C. Read also tungsten and a tungsten wire has resistance r at 20 The resistance of a wire at 20C is 20.
27This circuit has a total wire resistance wire 1 wire 2 of 30 at standard temperature. Again we need to know what the resistance R 0 is at the reference temperature T 0.

The impedance transformation is proportional to the turns ratio squared so a simple mains to 12V transformer ratio 120 but you could actually measure the ratio from the voltage ratio and calibrate the system would give you a multiplication factor of 400 so you would then be measuring a resistance of a few hundred Ohms.
The temperature coefficients of resistivity of copper and tungsten are 390 10-3 C1 and 450 10-3 C1 respectively. For example the electrical conductivity of copper is 595 107 S m and the electrical resistivity of copper is 168. Assume the initial temperature is 200circ mathrmC. The tungsten wire filament has a resistance of 240 ohms when this bulb is operated at a potential difference of 120 volts. Its resistance temperature coefficient is 00045C.
