In a conductor, increasing the length will cause resistance to

• A. Decrease
• B. Increase
• C. Stay the Same
• D. Fluctuate

Answer: (B)

Increasing the length increases resistance because resistance scales with how much resistive material the current must pass through. For a uniform conductor, R = ρL/A, so with the same material (ρ) and cross-sectional area (A), longer length (L) means higher resistance in direct proportion. Intuitively, electrons travel through more material and encounter more collisions, facing more opposition to flow. If the length doubles, the resistance doubles, assuming temperature and other factors stay the same.
