Ohm's law applies to:
Correct answer: D. Conductors
- A. Semiconductors
- B. Vacuum tubes
- C. Carbon resistors
- D. Conductors
Explanation
According to Ohm's law, Resistance of a conductor is directly proportional to its length. That is, when the length of conductor is tripled, its resistance also gets tripled. It is applicable only to conductors. Hence, Ohm's law is not applicable in case of insulators.

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.
