The change in resistance of metallic conductor at temperature below 0 degrees is:
Correct answer: C. Linear
- A. Non-linear
- B. Curve
- C. Linear
- D. Curvilinear
Explanation
The resistance increases as the temperature of the metallic conductor increases. The graph between resistance and temperature is linear for both increasing and decreasing temperatures.

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.
