In terms of R the resistance of the second wire is A 16 x 10-4C B36 x 10-2C C 16 x 10-1C D 36 x 101C 21A 2700-ohm resistor in an electric circuit draws a current of 24 milliamperes.
A tungsten wire has resistance R at A second tungsten wire at Has twice the length and half the cross-sectional area of. The tungsten wire filament has a resistance of 240 ohms when this bulb is operated at a potential difference of 120 volts. Assume that the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here and find the temperature of the hot filament. Here we can use the 25 C as our reference temperature. This tungsten wire filament has a resistance of 19 ohms at a temperature of 20C. The temperature coefficients of resistivity of copper and tungsten are 390 10-3 C1 and 450 10-3 C1 respectively.
