    Apr 02, 2021 Resonance is an advantageous property for many circuit applications, but not for grounding. The input impedance presented by the grounding and bonding conductors at resonance is high or low, depending on whether the circuit is parallel or series resonant. Resonance occurs at values equal to integer multiples of ʎ/4 (ʎ/4, ʎ/2, (3/4)ʎ, ʎ, etc.)

    May 17, 2021 In complex form, the resonant frequency is the frequency at which the total impedance of a series RLC circuit becomes purely “real”, that is no imaginary impedance’s exist. This is because at resonance they are cancelled out. So the total impedance of the series circuit becomes just the value of the resistance and therefore: Z = R
