What is the difference between an ordinary transformer and resonant coupling energy transfer?
Coupling field is link between electrical and mechanical energies in electromechanical energy conversions. If the output is mechanical (motor), coupling field reacts with input electrical energy in terms of Back EMF which opposes the input. Coupling field absorbs energy from electrical system, converts and delivers mechanical energy. If output is electrical (generator), coupling field reacts with input mechanical energy in terms of Magnetic Drag which opposes the input. Coupling field absorbs energy from mechanical system, converts and delivers electrical energy.
Coupling is an important metric. If the module P. is tightly coupled to module Q. then a change to module P. may require a corresponding change to module Q. If this change is made, as required, during integration or postdelivery maintenance, then the resulting product functions correctly; however, progress at that stage is slower then would have been the case had coupling been looser. It has been shown that the stronger (more undesirable) The coupling, the greater the fault proneness. In other words, it is easy to believe that strong coupling can have a deleterious effect on maintainability.
Piezoelectric materials typical experience a reduction in the remnant polarization. The effectively reduces the coupling between mechanical and electrical energy reducing the electro-mechanical coupling coefficient.

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
transformer coupling
rc coupling is a coupling that involves capacitor aand resistor
no.transformer coupling gives higher gain
Direct coupling
There are several projects that can be done to find out the effect of coupling on rust. One example would be to experiment on several different types of alloys to see which rusts least.
1)rc coupling 2)transformer coupling 3)direct coupling
