- How long is a tungsten wire if it has a diameter of 0.179 x 10-3m and a resistance of 2.63 k2? The resistivity of tungsten is 5.62 x 10-* 2-m. length of the wire:Resistance depends on the size and shape of a conductor. We expect a long wire to have higher resistance than a short one (everything else being the same) and a thicker wire to have a lower resistance than a thin one. Resistance also depends on the intrinsic property of the conductor called the resistivity. If the resistivity of a particular wire is 21.63x10-8 · m, the wire is 11.12mm in length, and the radius of the diameter of the wire is 1.62m, what is the resistance of the wire in units of Ohms (N)? Note: It is understood that the unit of your answer is in Ohms (N), however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.
