Question

What will be the new resistance of a conductor if its area of cross-section is doubled?​

Answer 1

Answer:

so if length is doubled resistance will also get doubled i.e resistance is 4 times that of original resistance. now, the resistance of a conductor is inversely proportional the area of cross section. The larger the cross sectional area, the lower the resistance since the electrons have a larger area to flow through.

Answer 2

Answer:half of the initial resistance

Explanation:

resistance of a conductor is inversely proportional to cross sectional area of the conductor.
