WitrynaImpedance Z of the above circuit is. Z=R+ jL-jC. Z=R+j(L-1C) The circuit is entirely resistive while it is in resonance. This signifies that during the resonance state or at the resonant frequency, the imaginary component of the impedance Z will be zero. Always keep this in your mind while evaluating the resonant frequency for a given circuit. Witrynaplot, the negative imaginary component of impedance (y-axis) is plotted against the real component of impedance (x-axis). Different regions of the Nyquist plot correspond to various chemical and physical processes occurring in the battery (see . Figure 2).
