Homework Statement



Quick one guys, I am very confused about the impedance of a RLC circuit. Say when you have more than one resistor or more than one capacitor or inductor in different combination, you get a impedance with two parts(imaginary which is the reactive part and the resistive part) when the circuit is in resonance, how do I find the actual impedance because all the reactive parts cancels out.

Homework Equations



and what is the behaviour of resistor above resonance frequency...?

The Attempt at a Solution



I am stuck....

Write the equation for a parallel RLC circuit, and solve for the Z(resonance). What do you get?

Do the same for a series RLC circuit -- what do you get for Z(resonance)?
