a. Table gives th
a. Conductor has very low resistance in order to allow the free flow of electrons through them. Therefore Material A is the best conductor because it has the low resistivity which implies low resistance.
Insulators are the materials having high resistance. Therefore Material B is the insulator because it has the highest resistivity which implies high resistance.
b. The Resistivity of the wire will not change with the change in length. Resistivity is a property of the wire, it doesn't depend upon it’s length or cross-sectional area.
