LC Circuit & Oscillations
An electrical circuit containing an inductor and capacitor that exchanges energy periodically between the electric field of the capacitor and magnetic field of the inductor.
Governing formula
f₀ = 1 / (2π √(L C)), E_total = ½ C V² + ½ L I²
SI unit
Hz (Frequency), J (Energy)
In depth
Acts as an electrical resonator oscillating at natural frequency f₀, analogous to a mechanical pendulum exchanging potential and kinetic energy.
Examples in the real world
RF tank circuits in radio transmitters and clock signal generators in radio frequency communications.
