Self-inductance of a coil depends on
Athe current passing through it
Bits geometry and number of turns
Cthe voltage across it
Dthe surrounding temperature
Answer & Solution
Correct answer: B. its geometry and number of turns
1. L = NΦ/I; for a fixed geometry the ratio Φ/I is determined by the configuration.
2. Therefore L depends on number of turns and geometric factors (area, length, core).
3. It is independent of the instantaneous current value.
