alleryResistance is inversely proportional to the conductor's:
ALength of the wire
BTemperature rise
CApplied potential
DCross-section area
Answer & Solution
Correct answer: D. Cross-section area
1. A longer wire raises resistance.
2. A wider wire lowers it.
3. So R is inversely proportional to the cross-sectional area.
4. The answer is cross-section area.
