The magnitude of the current in metals is proportional to the potential difference across it as long as the temperature of the conductor is kept constant is known as:
Correct answer: C. Ohm's Law
- A. Joule's Law
- B. Gauss Law
- C. Ohm's Law
- D. Ampere's Law
Explanation
The current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor.

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.
