Self inductance of a solenoid is directly proportional to ___

A

current passing through solenoid.

B

its length.

C

its area of cross-section.

D

reciprocal of its area of cross-section.

Text Solution

Verified by Experts

The correct Answer is:
C
Self inductance of a solenoid is given by `L=(mu_0N^2A)/l`
Hence we have the relation `L prop A`
