Question

select the non -ohmic conductor . a) iron. b) copper. c) aluminium.d) silicon.​

Answer 1

non ohmic conductor

coper

I hope this is write answer

Answer 2

Explanation:

Silicon is a semiconductor..

Aluminium,iron,copper is a conductor.

• Semiconductors are the substance whose conductivity lies b/w conductor and insulator.

• Conductors are the substance that allow electricity to pass through them.eg:iron,

• Insulator are the substance that do not allow electricity to pass through them.

• If a device behaves in a way that is NOT described by Ohm's law, (i.e. the resistance is not constant, but changes in a way that depends on the voltage across it.) The device is said to be non-Ohmic. In this case V versus I graph is not a straight line, but has some curvy shape.

I think your answer is silicon.
