Question
Physics Question on Current electricity
The resistance of a conductor decreases with increase in cross-sectional area 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
If both assertion and reason are true and reason is the correct explanation of assertion
Explanation
Solution
Increasing the cross sectional area increases the space available for electrons to flow, which decreases the resistance of the conductor
