Polarization Hysteresis Ciruit

welatiger

Hi all,
I want to measure electric polarization hysteresis loop so i need the electric circuit to measure it.
The circuit mostly contains a resistor and a capacitance, i need to what is the exact value of them ?

Please tell me if there is a reference for that
Thank you

note : the circuit called Sawyer-Tower Circuit

Enthalpy

Depending on the material, charge release can be very slow, for instance in electrolytic capacitors. In such a case, the only sensible circuit is to disconnect completely the capacitor, keep it clean in a dry atmosphere, and reconnect it only for the measure. It can take several days before the last 0.1% of charge is released, while the first 20% which are absorbed by polarization are available in few seconds.
