The resistance of a conductor at absolute zero ( 0 K) is
Correct answer: A. Almost zero
- A. Almost zero
- B. Almost infinite
- C. No prediction at all
- D. May increase or decrease
Explanation
At absolute zero i.e, 0K which is also the minimum temperature, the Resistance of the conductor becomes minimum but not exactly zero.

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.
