what is the difference between electrical and mechnical damping factor?
what i mean is that,
what is mean by electrical damping? the mechnical damping i know that is related to those frction, air resistance... how about electrical?

i have seen some paper had used those parameters,but i have no idea about that.
even i can't find in wiki..

can anyone help me!thxxxx so muchhh

They analogs of each other and are Resistance...

In the mechanical system you might have some air in that cylinder that "damps" the oscillation of the piston. In an electrical system you'd have a resistor that damps the oscillation of an LC circuit.

In this case, the electromechanical damping is motional damping with induced eddy currents in moving conductors in magnetic fields. See

Thx you all to answer this question!reli thxxx

but, since i m doing a mini power generator. can i just neglect the electrical damping one? because i have seen some paper that some may contain this and some may not.
and i am not so familiar with this part of the knowledge..so i m so confuse to proof those equation in order to have a response function with the
displacement input and the induced voltage output system.

and so thankyou that i have more idea about the electrical damping part which is related to the eddy current. =]
reli thxxx!
