The resistance of the conductor increase with the increase in its
Correct answer: B. Length
- A. Cross-sectional area
- B. Length
- C. Diameter
- D. None of these
Explanation
The resistance of a conductor is directly proportional to its length. When the length of a conductor increases, there is more material for the current to travel through, leading to increased collisions between charge carriers and higher resistance. Therefore, an increase in length results in an increase in resistance.

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.
