Question

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 explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (D)

The given graph shows the $V-I$ graph of a good conductor Ohm’s law states that, current flowing through a conductor is directly proportional to the voltage between the ends of a given conductor, i.e. $V\propto i$
