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.

R= (specific resistance *length) /area.

Area = small (given).

Resistance high which implies that high heat (H proportional to R).
