Assertion: For good conductors, the I-V ...

Assertion: For good conductors, the I-V graph is a perfect straight line inclined to current axis.
Reason: By Ohm's law, voltage across the ends of a conductor is directly proportional to the resistance of the conductor.

A

If both assertion and reason are true and reason is the correct explantion of assertion.

B

If both assertion and reason are true and reason is not the correct explantion of assertion.

C

If assertion is false but reason is true.

D

If assertion is true but reason is false.

Text Solution

Verified by Experts

The correct Answer is:
D
The given graph shows the V-Igraphofagoodconductor. Ohm's law states that, current j flowing through a conductor v is directly proportional to the voltage between the ends of a given conductor. i.e. `V prop I`
