Question

Assertion : The resistance of a conductor decreases with increase in cross-sectional area
Reason : On increasing the cross-sectional area of a conductor, more current will flow through 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: (A)

Increasing the cross sectional area increases the space available for electrons to flow, which decreases the resistance of the conductor
