Using the relation,

substituting values,

or,

So,
Self-inductance of coil 1 = 0.133 H

Self-inductance of coil 2 = 0.033 H
Mutual inductance of the coils = 0.04 H
Coefficient of coupling = 0.606

1.19 ELECTRICAL CIRCUIT ELEMENTS

Resistors, inductors, and capacitors are the three basic circuit parameters or

circuit components of any electrical network. Resistors can be wire-wound
type or carbon-moulded type. When current flows in a resistance, heat is

produced, which is dissipated. The heat is produced because friction between
moving free electrons and atoms obstruct the free flow of electrons producing
electric current. A resistor is an element that dissipates energy as heat when

current flows through it.
