initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high
control coupling content coupling common coupling data coupling external coupling message coupling
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
no.transformer coupling gives higher gain
Direct coupling
F**k you! A********e ! U f**********g moron. If i would have known the answer then i would'nt have asked the question.

The measurement of stiffness of the electromagnetic coupling between the rotor and the stator is carried out by the synchronizing power coefficient. If the value of Psyn is large, the coupling is stiff or rigid. For a too rigid coupling, with change of load or supply, the machine will be under shock which may damage the rotor of the winding
The coefficient of coupling between two air core coils depends on factors such as the physical distance between the coils, the number of turns in each coil, and the alignment of the coils relative to each other. It also depends on the relative orientation of the magnetic fields generated by each coil.

The coefficient of coupling between two air coils depends upon factors such as the distance between the coils, the number of turns in each coil, the cross-sectional area of the coils, and the orientation of the coils with respect to each other. It also depends on the permeability of the medium between the coils and the relative alignment of the magnetic fields generated by each coil.
transformer coupling
rc coupling is a coupling that involves capacitor aand resistor
no.transformer coupling gives higher gain
Direct coupling
1)rc coupling 2)transformer coupling 3)direct coupling
