What are the effects of the coefficient coupling in a mutual inductive circuit?
Answers
Coefficient Of Coupling. The fraction of magnetic flux produced by the current in one coil that links with the other coil is called the coefficient of coupling between the two coils. .k=1, when the flux produced by one coil, completely links with the other coil and is called magnetically tightly coupled.
When the coefficient of coupling, k is equal to 1, (unity) such that all the lines of flux of one coil cuts all of the turns of the second coil, that is the two coils are tightly coupled together, the resulting mutual inductance will be equal to the geometric mean of the two individual inductances of the coils.
I HOPE IT HELPS YOU.
Answer:
The effects are as follows:
When the coefficient of coupling, k is equal to 1, (unity) such that all the lines of flux of one coil cuts all of the turns of the second coil, that is the two coils are tightly coupled together, the resulting mutual inductance will be equal to the geometric mean of the two individual inductances of the coils.
For determining the Mutual Inductance between the two coils, the following expression is used
M = Em/dI1/dt
