so much for a group about electrical engineering

Hi tbone,

You can probably find some good descriptions of resonance in electrical

circuits by doing a search on the Internet. I went to Google

(

http://www.google.com), typed in "electric circuits resonance" without

quotes and found a pretty good site right off the bat,

http://www.ibiblio.org/obp/electricCircuits/AC/AC_6.html
and another one,

http://www.intuitor.com/resonance/circuits.html
If you'd prefer books, I'd recommend _Schaum's Guide to Electric Circuits_

by Edminster. _Engineering Circuit Analysis_ by Hayt and Kemmerly, and

_Network Analysis_ by Van Valkenberg as excellent sources.

To really understand resonance it helps to be able to understand the

mathematical models used in the standard descriptions. The typical math

model for a simple RLC resonant circuit involves a second-order linear

ordinary differential equations with constant coefficients. If you need

help with understanding what that means, find an introductory text

(sophomore college level, usually) on ordinary differential equations and

they'll usually talk about resonance when they get to solution of

second-order ordinary differential equations whose auxiliary equations have

complex conjugate solutions.

Also, realize that resonance is not just a phenomenon observed in electrical

circuits, but also in many types of physical systems. For example, most of

the texts I've seen on linear systems theory you'll see electrical

parameters (resistance, capacitance, etc.) compared with mechanical,

thermal, and fluid systems. The math is the same for certain arrangements

of elements in each type of system.

Try looking up some of this information on your own and ask the question(s)

again if you still have them after that.

Good luck and happy holidays,
