coil resistance of an inductor

[squeak07]

i just want to know if what is the effect of the coil resistance of an inductor in a circuit..?
please answer me.
thank u.

Is this your homework?

One answer lies twixt R and P, but depending on the circuit, this may not be the major issue, as it may have to do with P when I go through R.

nope, not a homework..

In that case I'd consider the "Q" of the inductor and (I^2)R losses.

Both of which you may have gleaned from my previous post

edit: Depending on the circuit, one or both of the above may be important (or even critical) or, alternately, of no particular concern...

If this is a basic question, the basic answer is:
It depends on your operating frequency.

As Shrtrnd said ... it depends on frequency ...
