The inductance of solenoid depends upon the:
Correct answer: D. All of above
- A. Area of cross section
- B. Length of solenoid
- C. Number of turns
- D. All of above
Explanation
Therefore, the correct option is "All of the above" as the inductance of a solenoid depends on the area of cross section, the length of the solenoid, and the number of turns.

About Transformers
Transformers transfer alternating electrical energy between coils by mutual induction, with voltage ratio determined by the turns ratio. The topic covers step-up and step-down transformers, current changes, ideal power conservation and practical losses such as heating and flux leakage. A transformer requires changing magnetic flux, so it does not operate with steady direct current.
