Resistance of a conductor depends upon
Correct answer: C. length
- A. temperature
- B. nature of a conductor
- C. length
- D. None of these
Explanation
Option C is correct since the resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. Resistance also depends on the material of the conductor.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
