Frequently Asked Questions
What is LC resonance?+
At resonance, the inductive reactance (XL = 2πfL) equals the capacitive reactance (XC = 1/(2πfC)), and energy oscillates between the inductor and capacitor. Resonant frequency f = 1 / (2π√(LC)).
Where is LC resonance used?+
Radio receivers (tuning circuits), RF amplifiers, oscillators, band-pass/stop filters, and impedance matching networks all rely on LC resonance.
