Resistances (e.g. to charge transfer) give a response in phase with the voltage perturbation; capacitances (e.g. double layer) give a response 90\u00b0 out of phase; combinations of resistances and capacitances give phase angles between 0 and 90\u00b0. Plots of the out of phase vs. the in phase component of the impedance for all the frequencies tested are called complex plane (or Nyquist) plots. Plots of the phase angle and the magnitude of the impedance vs. the logarithm of perturbation frequency are called Bode diagrams. Complex plane plots are the more commonly used for electrochemical sensors.@en"] OSWd30d9de0b9bf4919a0220394df9c3672# ERR0cf8c53d7c740a4d5c6eafb6f7e19495
