Resistance directly depends upon:
Correct answer: B. Length
- A. None
- B. Length
- C. Nature of material
- D. Temperature
Explanation
Resistance is directly proportional to the length of the wire the current is passing through. Hence, the correct answer is length.'Resistivity' depends on the temperature and the nature of the material.

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.
