A:
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 70.26x10-8 Ω ⋅ m, the wire is 44.47mm in length, and the radius of the diameter of the wire is 1.95m, what is the resistance of the wire in units of Ohms (Ω)?

- A copper wire has a resistance of 15 Ω at some temperature. An aluminum wire has 3 times the length and 5 times the radius of the copper wire. The resistivity of copper is 0.7 times that of aluminum. What is the resistance, in Ω, of the aluminum wire at the same temperature? Round your answer to 0 decimal places.Determine the length (in mm) of a gold conductor that has a resistance of 0.019 Ω and a cross-sectional area of 2.1 x 10-9 m2. The resistivity of gold is 2.2 x 10-8 Ω-m [round your final answer to one decimal place]. An aluminum conductor with the same length and area as in Question above would have a higher resistance than the gold conductor. The resistivity of aluminum is 2.6 x 10-8 Ω-m. True or falseAluminum and copper wires of equal length are found to have the same resistance. What is the ratio of their radii?
