1.	The example of a non-ohmic resistance isA) Copper wireB) TransistorC) DiodeD) Tungsten wire
Answer» Correct options are:- (B) and (C) Transistors and Diodes are examples of non- ohmic resistances, as their V-I graph is constant curve. The correct option is (B) transistor and (c) Diode. A non-ohmic resistance is a resistance which does not follow the Ohm’s law. Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The main Characteristic of Ohmic resistance is the VI curve which is a straight line. The diode does not have a straight line as a VI curve. The copper wire has a straight line as a VI graph. The filament lamp has a straight line as a VI graph. The carbon resistor has a straight line as a VI graph. So, the diode is a non-ohmic resistance.

Answer» Correct options are:- (B) and (C)

Transistors and Diodes are examples of non- ohmic resistances, as their V-I graph is constant curve.

The correct option is (B) transistor and (c) Diode.

A non-ohmic resistance is a resistance which does not follow the Ohm’s law. Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

The main Characteristic of Ohmic resistance is the VI curve which is a straight line.

The diode does not have a straight line as a VI curve.

The copper wire has a straight line as a VI graph.

The filament lamp has a straight line as a VI graph.

The carbon resistor has a straight line as a VI graph.

So, the diode is a non-ohmic resistance.
