(2) Alloys

(3) Insulators
(4) Semiconductors​

Answer 1

Answer:

semi conductors is the answer.

Answer 2

The correct answer is option (3) Insulators as they have the maximum resistivity at a particular temperature.

• The reason for insulators having maximum resistivity is because they have materials in them which provides high resistance to the flow of electric current. As such, insulators have a low conductivity which is used to sperate different electrical components to keep the electric charges contained and prevent short circuits from happening.

• On the other hand, Conductors have have a low resistivity, which allows the passage of electric current with less resistance.

• Semiconductors and alloys are in between. They have medium level of resistivity and it majorly depends on their composition and the temperature at which they are operating.
