Resistivity of a conductor depends upon
Correct answer: A. temperature
- A. temperature
- B. length
- C. cross-sectional area
- D. None of these
Explanation
The resistivity of a material depends on its nature and the temperature of the conductor. The resistivity of a material doesn't depend on its shape and size (length and area).

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.
