Question

Given the resistivities below, which matedal is best described as an insulator?

O A. 4.5 Ω•m
O B. 2.8 x 10-8 Ω•m
O c. 3.2 x 108 Ω•m
O D. 1.7 x 10-8 Ω•m​

Answer 1

C. 3.2 x 10^8 Ω•m

Step-by-step explanation:

An insulator is a material that resists the flow of electricity.

In the given data the material with the highest resistivity is the best insulator

3.2 x 10^8 Ω•m
