Question

A piece of wire is measured to have a resistivity in the order of 10^19 Ω m. (Note: 10^19=10 to the power 19) What should its material be classified into? a) Alloys b) Insulators c) Good conductors d) Poor conductors

Answer 1

Answer:

. Poor conducter

Answer 2

Explanation:

Conductors allow the maximum electric current to pass through them and so they have the least resistivity or most conductivity. On the other hand, an insulator does not allow the electric current to pass through it, thus it has the most resistivity. Alloys have more resistivity than the conductors but less than the insulator.

Thus correct order of resistivity is : Conductors → Alloys → Insulators
