help badly needed!

Hey guys, please help me about this topic:

What are the applications of LRC circuits (Inductor-Resistor-Capacitor circuit)?

I've searched many sites but I haven't found any applications and explanation on how these applications work using LRC circuits. I've also read the books that are available here in our school but they don't have applications included in the text. I hope that you can help me with this topic. Thanks!

You can search google for ( "RLC","Filters" ), but start here -

The RLC circuits may be used as a bandpass or band-stop filters.

or more generally - http://en.wikipedia.org/wiki/Electronic_filter

Also look at LC circuits.
