You need to prepare a 0.107 × 10-3 m diameter tungsten wire with a resistance of 3170 Ω. How long must the wire be? The resistivity of tungsten is 5.62 × 10-8 Ω·m. You need to prepare a 0.107 x 103 m diameter tungsten wire with a resistance of 3170 Ω·How long must the wire be? The resistivity of tungsten is 5.62 x108 m. Number Im
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.
The heating element in a hair dryer is essentially a wire whose resistance causes it to become red-hot when a current exisits in it. Such wires are usually made of nichrome (a nickel-chromium alloy), whose resistivity is p=1.0*10^-6 ohm*m. (a) Suppose one such wire has a diameter of 0.30 mm and a resistance of 9.0 ohm. What is the length of the wire? (Note that wires like this in a hair dyrer tend to be coiled around to save space)...
What length of copper wire .6 mm in diameter has a resistance of 1 Ohm?
A cylindrical tungsten filament 15.0 cm long with a diameter of 1.10 mm is to be used in a machine for which the temperature will range from room temperature (20 ∘C) up to 120 ∘C. It will carry a current of 13.5 A at all temperatures ( Resistivity of tungsten at 20 ∘C is 5.25×10−8Ω⋅m , the temperature coefficient of resistivity at 20 ∘Cis 0.0045 ∘C−1 ) Part B What will be its resistance with that field? Express your answer...
