The resistance of a certain copper wire is 0.4 Ω. Determine the resistance of a tungsten wire having the same dimensions as the copper wire. Express your answer to three significant figures and include the appropriate units.
A wire with a resistance of 50 Ω is drawn through a die so that its new length is 2 times its original length. Find the resistance of the longer wire, assuming that the resistivity and density of the material are unchanged.
A copper wire has a resistance of 0.500 Ω at 20.0°C, and an iron wire has a resistance of 0.520 Ω at the same temperature. At what temperature are their resistances equal? The temperature coefficient of resistivity for copper is 3.90 *10^-3(°C)−1 and for iron it is 5.00 *10^-3(°C)−1.
A copper wire has a resistance of 0.540 Ω at 20.0°C, and an iron wire has a resistance of 0.579 Ω at the same temperature. At what temperature are their resistances equal? The temperature coefficient of resistivity for copper is 3.90 10-3(°C)−1 and for iron it is 5.00 10-3(°C)−1.
