After the connections are made, the test voltage is applied, and the IR is read at two different times: Usually either 30 and 60 sec, or 60 sec and 10 min. The latter reading is divided by the earlier reading, the result being the dielectric absorption ratio. The 10 min./60 sec. ratio is called the polarization index (PI).

Gauss''s law is that the total (D)-flux arising from a charge is equal to the charge, so that in this geometry (D = sigma), and this is not altered by the nature of the dielectric materials between the plates. Thus, in this capacitor, (D = CV_0/A = Q/A) in both media. Thus (D) is continuous across the boundary.
Capacitors. Capacitors are passive electronics components that store electrical charge. There are two common types of capacitors – non-polarized and polarized. Non-Polarized Capacitors. Non-polarized capacitors don''t have polarity, so it doesn''t matter which side is connected to positive and which side is connected to negative. …

In order to pull the dielectric out of the capacitor requires that work be added to the system (equivalent to increasing the plate separation in Example 2.4.1), while allowing the dielectric to be pulled into the capacitor removes energy from the system in the form of work done on the dielectric. This analysis can be performed "in reverse" to ...
