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 N·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 (1)?

Question
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.
