Electro Magnetic Induction And Alternating Currents Question 285
Question: Assertion : When two coils are wound on each other, the mutual induction between the coils is maximum. Reason : Mutual induction does not depend on the orientation of the coils.
Options:
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Show Answer
Answer:
Correct Answer: C
Solution:
The manner in which the two coils are oriented, determines the coefficient of coupling between them. $ M=K^{2}.L_{1}L_{2} $ When the two coils are wound on each other, the coefficient of coupling is maximum and hence mutual inductance between the coil is maximum.
