Self-inductance L of a coil is the proportionality between:
AEMF and the steady current
BFlux linkage Φ and current I
CMagnetic field and loop area
DResistance and AC frequency
Answer & Solution
Correct answer: B. Flux linkage Φ and current I
1. Self-inductance L: Φ_linkage = L I.
2. By Faraday, EMF = − L dI/dt — the back-EMF when current changes.
3. SI unit: henry (H) = V·s/A.
