alleryResistance of a wire is inversely proportional to what?
AIts total length
BIts colour shade
CIts cross-section area
DIts melting date
Answer & Solution
Correct answer: C. Its cross-section area
1. For a given material, resistance is inversely proportional to cross-sectional area.
2. Resistance is proportional, not inverse, to length.
3. Colour has no effect.
