10. | Inductance is indirectly proportional to the square of the number of turns, the permeability, and the cross-sectional area of the core. |
|||||||||

Your Answer: Option (Not Answered) Correct Answer: Option B Explanation: Some factors that affect the inductance of a coil include: 1. The inductance is proportional to the square of the number of turns; 2. The inductance increases directly as the permeability of the core material increases; 3. The inductance increases directly as the cross-sectional area increases; and 4. The inductance decreases as its length increases.
