How to get resistance value from Nyquist plot?

I measured resistance of my solid electrolyte with Au as blocking electrode. Real impedance value did not start from zero value, rather higher than zero value. Should I subtract that value of real...

What do the positive values of imaginary part in nyquist plot mean?

Usually when we measure the impedance for solid state electrolytes then they show a semicircle that starts at a high frequency and a line at a low frequency. Semicircle represents the bulk and the...
