Three.Terminology and Definitions
a.Contact Resistance: Refers to the electrical characteristics of the contact area between two objects, which are in relative proximity and limit the flow of stable current through electrodes./Electrodes/Sheet and sheet/Contact between sheets.
b.Volume Resistance: Refers to the ohmic resistance of an electrical conductor.
c.Total Resistance: Refers to the resistance measured between two electrodes (including bulk resistance and contact resistance).
d.Set Resistance: Refers to the resistance between two electrodes without metal plates; direct contact between the two electrodes.
e.Transition Resistance: Refers to the total resistance minus the set resistance.
