Q-00001721
How does the resistance of a conductor change with its thickness?
1
It remains constant.
2
It decreases.
3
It increases.
4
It becomes zero.
Answer and Solution
Answer
B. It decreases.
Solution:
The resistance of a conductor is inversely proportional to its cross-sectional area, which includes thickness. Therefore, as the thickness of a conductor increases, its resistance decreases, allowing for easier flow of electric current.
