Wire cross-sectional area is inversely proportional to resistance and resistance produces heat, as cross-sectional area decreases the resistance increases.
This resistance produces more heat with small cross-sectional area.
This resistance produces more heat with small cross-sectional area.

R= (specific resistance *length) /area.
Area = small (given).
Resistance high which implies that high heat (H proportional to R).
Area = small (given).
Resistance high which implies that high heat (H proportional to R).
