How Do You Calculate Impedance in a Resonant RLC Circuit?

AI Thread Summary
In a resonant RLC circuit, impedance consists of both a resistive and a reactive component. At resonance, the reactive parts cancel each other out, simplifying the calculation of total impedance. For a parallel RLC circuit, the impedance can be found using the appropriate equations, while a series RLC circuit requires a different approach to determine its resonance impedance. Additionally, the behavior of resistors above the resonance frequency can affect overall circuit performance. Understanding these principles is essential for accurately calculating impedance in complex RLC configurations.

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)?
