The ohm's law is applicable if:
Correct answer: D. Temperature of the conductor remains same
- A. Temperature of the conductor becomes infinite
- B. Temperature of the conductor increases
- C. Temperature of the conductor decreases
- D. Temperature of the conductor remains same
Explanation
"The current flowing through a conductor is directly proportional to potential difference across its ends provided the physical state such as temperature etc. remains constant." Hence, option D is correct.

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.
