Which of the following is the correct conceptual statement of Ohm's Law (under constant physical conditions like temperature)?
- 1The current through a resistor is directly proportional to its resistance.
- 2The potential difference across the ends of a conductor is directly proportional to the current flowing through it.✓
- 3If the potential difference across the ends of a conductor is 1 V and the current is 1 A, then the resistance is 2 Ω.
- 4The potential difference across the ends of a conductor is inversely proportional to the current flowing through it.
Correct answer
The potential difference across the ends of a conductor is directly proportional to the current flowing through it.
