The resistance of the conducting material depends upon
Correct answer: D. All
- A. The nature of the conductor
- B. Dimension of the conductor
- C. Physical state of the conductor
- D. All
Explanation
The resistance of a conducting material depends on several factors, including:a. The nature of the conductor: Different materials have different resistivities, which affect the resistance.b. Dimensions of the conductor: The length, cross-sectional area, and shape of the conductor influence the resistance.c. Physical state of the conductor: Temperature, pressure, and other physical conditions can impact the 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.
