my question is:

consider a general resonance circuit( i mean, not just a simple parallel RLC);

does the impedance has a peak(max) at resonance freq?? and (if yes) why it must has a max at that freq? how you relate the "

*imaginary must be zoro*" condition to "

*impedance is maximum*" condition?

3 questions

thank you
