Conductivity depends on:
Correct answer: A. Temperature and nature of material
- A. Temperature and nature of material
- B. Length
- C. Area
- D. All
Explanation
Conductivity, like its inverse resistivity, is an intrinsic property of a material. It depends on factors like the number of free charge carriers and their mobility, which are determined by the nature of the material and its temperature, not its physical dimensions.

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.
