Thanks a lot Anand, Is there any way to get an estimate of phase shift at 5Hz from this datasheet. You know I want to calculate impedance from phase shift of current relative to voltage waveform, so I want to calculate error(at least an estimate) of calculations. is it in order of 10, 1, 0.1, 0.01, 0.001, Can I extrapolate?
Thanks again.
i'm not that well-versed in this topic.........
but the method is you can find the pole from the graph... now write the transfer function and find the time constant (ζs) and since the system is a single pole system the phase shift can be written as -tan(ωζs)....... then subtitute 2Π(5) for ω......
