Question

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.

Explanation / Answer

option A is correct,

all the wires are of same material will have same resistiuvity.

reistance i9s inversely proportional to thickness of wire,

so decreasing thickness means increasing resistance
