Antennas and Resonant Circuits (Tank Circuits)
The resonant frequency (f_0) of the RLC circuit is the frequency at which the amplitude of the current is a maximum and the circuit would oscillate if not driven by a voltage source. By inspection, this corresponds to the angular frequency (omega_0 = 2pi f_0) at which the impedance Z in Equation ref{15.15} is a minimum, or when
