STANDARD Physics Self Inductance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The self inductance of a long solenoid cannot be increased by
A
increasing its area of cross section
B
decreasing its length
C
increasing the current through it
D
increasing the number of turns in it
Correct Answer
Option C
Detailed Explanation
The self inductance of a long solenoid is given by L = (μ₀N²A)/l, where N = number of turns, l = length, and A = cross-sectional area. The inductance does not depend on the current flowing through it.
