AIIMS 2018 Physics Inductance MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Assertion : When number of turns in a coil is doubled, coefficient of self-inductance of the coil become four times.

Reason : This is because LN2L \propto N^2.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Correct Answer

Option D

Detailed Explanation

The relationship LN2L \propto N^2 indicates that the self-inductance LL of a coil increases with the square of the number of turns NN. This means that if the number of turns is doubled, the self-inductance increases by a factor of four, illustrating the quadratic dependence. Options A, B, and C are not relevant to the question as they do not provide any information or context related to the relationship between self-inductance and the number of turns in a coil. Understanding this principle is crucial for analyzing inductive components in electrical circuits.
