Question

If a current of 1 A flows through a conductor, then according to Ohm's Law, the resistance of the conductor is:

पर्याय

• Exactly equal to 1 ohm regardless of the voltage

• Numerically equal to the potential difference across it

• Equal to the square of the potential difference

• Always zero

Answer 1

Special case: If I = 1 A, then from V = IR, we get V = R. This implies that the resistance of a conductor is numerically equal to the potential difference across it when 1 ampere of current flows through it.
