Answer:

Explanation:

Concept:

The inductor is an electrical component that is capable of storing electrical energy in the form of magnetic energy.  

The property of an electrical component that causes an emf to be generated by changing the current flow is known as inductance. Inductance is of two types

Self-inductance: This is the phenomena in which change in electric current produce an electromotive force in the same circuit, and is given by

Mutual inductance of the two coils is 50 mH if coils of  self inductance L₁= L₂= 50 mh  are perfectly coupled with each other

Given:
  • Two coils having self inductance
  • L₁= L₂= 50 mh
  • Perfectly coupled with each other

To Find:
  • Mutual inductance of the two coils

Solution:
  • M = k√L₁L₂
  • M = Mutual Inductance
  • k = Coefficient of coupling
  • k = 1   for  perfectly coupled coils

Apply formula M = k√L₁L₂ and substitute

L₁ = L₂ = 50 mH

and k = 1

M = 1 √(50 * 50)

M = 50 mH

Mutual inductance of the two coils is 50 mH
