STANDARD Physics Self Inductance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
If the number of turns per unit length of a coil of solenoid is doubled, the self-inductance of the solenoid will
A
remain unchanged
B
be halved
C
be doubled
D
become four times.
Correct Answer
Option D
Detailed Explanation
Self inductance of a solenoid is proportional to n², where n is the number of turns per unit length. Doubling n results in a fourfold increase in self inductance.
