Self-inductance of a solenoid is
- A directly proportional to the current flowing through the coil
- B directly proportional to the number of turns per unit length
- C directly proportional to its area of cross-section
- D inversely proportional to its area of cross-reaction
Answer & Solution
Correct Answer
(C) directly proportional to its area of cross-section
Step-by-step Solution
Detailed explanation
Self-inductance of a solenoid: \(L = \mu_0 n^2 A l\). \(L\) is directly proportional to its area of cross-section \(A\).
