Calculate the resonant frequency of an LC circuit involving an inductor and capacitor. Fundamental for radio tuning, oscillators, and filter design.
Resonance occurs when the inductive reactance equals the capacitive reactance. At this frequency, the circuit impedance is purely resistive.
LC circuits are the building blocks of radio tuners, allowing you to select a specific radio station frequency while rejecting others.
f = 1 / (2π√LC)
