Physics · Electromagnetic Induction
Two coils are said to have a mutual inductance of 1 henry if:
- 1A current of 1 ampere in one coil produces 1 tesla magnetic field in the other.
- 2A current of 1 ampere in one coil generates a flux of 1 weber in the other coil.
- 3A current change rate of 1 ampere per second in one coil produces 1 volt in the other.✓
- 4A current of 1 ampere in one coil produces flux-linkages of 1 weber-turn in the other coil.
Correct answer
A current change rate of 1 ampere per second in one coil produces 1 volt in the other.
