Question

State ohm's law white the necessary condition
fore its validity. draw its graph.​

Answer 1

Answer:

Ohm's law states that at a constant temperature, current 'I' through a conductor between two points is directly proportional to the potential difference or voltage 'V', across the two points. That is, V = IR. The necessary condition is that the temperature ahould be constant. The nature of the graph is a straight line.

Explanation:

Answer 2

Hey mate! Here is your answer:

Ohm's law states that at a constant temperature, current ‘I’ through a conductor between two points is directly proportional to the potential difference or voltage ‘V’, across the two points. That is,   V = IR. The necessary condition is that the temperature should be constant. The nature of the graph is a straight line. The physical quantity that can be determined is the gradient of the straight-line graph which is related to the resistance (R) of the conductor.
