The current passing through a conductor is directly proportional to the potential difference applied across its terminals, provided the temperature and other physical conditions of the conductor does not change.
Correct answer: D. Ohm's law
- A. Gauss's law
- B. Lenz's law
- C. Pascal's law
- D. Ohm's law
Explanation
Ohm's law states that: The current passing through a conductor is directly proportional to potential difference applied across its terminal, provided the temperature and other physical conditions does not change.

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.
