alleryInductance depends only on the coil's geometry and its:
ATotal charge
BWire colour
CCore medium
DApplied emf
Answer & Solution
Correct answer: C. Core medium
1. Inductance is fixed before any current flows.
2. Shape, turns and size all enter it.
3. So does the medium filling the coil.
4. The answer is core medium.
