A series RLC circuit has a resonance frequency of $2000 / \pi \mathrm{Hz} .$ When it is operating at a frequency of
$\omega>\omega_{0}, X_{L}=12 \Omega$ and $X_{C}=8.0 \Omega .$ Calculate the values of $L$ and $C$ for the circuit.

Key Concepts

Capacitive Reactance

Capacitive reactance is the opposition to the flow of AC current presented by a capacitor. It is inversely proportional to both the frequency and the capacitance, given by XC = 1/(?C). At higher frequencies, capacitive reactance decreases, making capacitors less resistive to AC, whereas at lower frequencies, it becomes more significant.

Inductive Reactance

Inductive reactance is the opposition offered by an inductor to the change in current in an AC circuit. It is directly proportional to the angular frequency and the inductance, expressed as XL = ?L. At higher frequencies, inductive reactance increases, which significantly impacts the behavior of AC circuits.

Resonance in RLC Circuits

Resonance occurs in a series RLC circuit when the inductive reactance and capacitive reactance are equal in magnitude, effectively cancelling each other. This condition minimizes the circuit's impedance and maximizes the current. The resonant frequency is determined by the values of the inductance and capacitance, and is given by the formula ?? = 1/?(LC) (or f? = 1/(2??(LC)) in Hertz).

Series RLC Circuit

A series RLC circuit is composed of a resistor, an inductor, and a capacitor connected in series. Its overall impedance is the combination of the resistance and the frequency dependent reactances of the inductor and capacitor. This circuit exhibits different behaviors at various frequencies, with significant changes occurring around its resonant frequency.
