Several wires of varying thickness are all made of the same material and all have the same length. If the wires are arranged in order of decreasing thickness, what can be said about the ordering of their resistance?

A. The wires will be arranged in order of increasing resistance.
B. The wires will be arranged in order of decreasing resistance.
C. The ordering of the resistances can not be determined because the resistivity is not given.
D. The ordering of the resistances can not be determined because the length is not given.

Expert Solution

All the wires are of the same material will have the same resistivity,

reistance i9s inversely proportional to the thickness of wire,

so decreasing thickness means increasing resistance.

The correct answer is option A.

Consider two wires made of the same material: 1) If both wires have the same radius, but wire 1 is half the length of wire 2, what is the resistance of wire 1 in terms of wire 2? 2) If both wires have the same length, but wire 1 has three times the radius of wire 2, what is the resistance of wire 1 in terms of wire 2?
