Solve this numerical..
Dear Student,
Given,
Resistance of a nichrome wire, R = 10 ohm
Let the length l and area of cross-section a of the nichrome wire be L and A respectively.
Then
Length of another nichrome wire, L' = 3L
Its area of cross-section, A'=4A
Let the resistance of the another wire be R'.
Then
Regards
