Question

Which among the following materials is not a conductor of electricity?
(a).copper rod
(b).Iron rod
(c).aluminium spoon
(d).glass rod​

Answer 1

Answer:

(d) glass rod

Explanation:

glass rod is the material that does not conduct electricity because it does not have the metalic properties .

and to be more specific.....

Conduction of electricity requires some mobility of electrons to move that potential charge through the material. Electrons in covalent and ionic compounds in glass are too tightly bound to the molecule to conduct electricity. Therefore, glass rod does not conduct electricity.

hope this helps u

Answer 2

Explanation:

Copper rod is good conductor of electricity.
