Question
Which has more resistance:
a thick piece of nichrome wire or a thin piece?
Advertisements
Solution
A thin piece of nichrome wire has more resistance because the resistance of a conductor is inversely proportional to its area of cross-section, i.e. R α 1 / A. The lesser the area of cross-section, the more the resistance.
