Pulsed methods and systems for measuring the resistance of polarizing materials

A method for measuring resistance of a polarizing material, the method comprising:

• providing a voltage divider circuit having a first resistive element of known resistance and the polarizing material of unknown resistance that are electrically-coupled in series to ground;
• electrically-coupling a processing unit to the voltage divider circuit;
• applying a voltage from the processing unit across said voltage divider circuit;
• measuring a voltage, using the processing unit, at a junction between the first resistive element and the polarizing material;
• and
• shorting the polarizing material after the voltage has been measured and before a new resistance measurement is made by using the processing unit to ground the junction between the first resistive element and the polarizing material.
