Question

An ohmmeter is a common device for measuring resistance. Using an ohmmeter, you find that a certain material has a very high resistance. This material is most likely what?

conductor
insulator
semiconductor
superconductor

Answer 1

An insulator

Step-by-step explanation:

Insulators have a very high resistance because the electrons of the insulator are bounded strongly with the nucleus. Hence it requires more voltage to move an electron from the valence band to the conduction band.
