STANDARD Physics Mutual Inductance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
If number of turns in primary and secondary coils is increased to two times each, the mutual inductance
A
becomes 4 times
B
becomes 2 times
C
becomes 1/4 times
D
remains unchanged
Correct Answer
Option A
Detailed Explanation
Mutual inductance is proportional to the product of the number of turns in the coils. Doubling the turns in both coils increases the mutual inductance by a factor of 4.
