Capacitor Charge and Discharge Questions and …
As seen in the current-time graph, as the capacitor charges, the current decreases exponentially until it reaches zero. This is due to the forces acting within the capacitor increasing over time until they prevent electron flow.. The …

Dielectric absorption is the name given to the effect by which a capacitor, that has been charged for a long time, discharges only incompletely when briefly discharged. Although an ideal capacitor would remain at zero volts after being discharged, real capacitors will develop a small voltage from time-delayed dipole discharging, a phenomenon that is also called dielectric relaxation, "soakage", or "battery action". For some dielectrics, such as many polymer films, the resulting voltage may b…
Dielectric Absorption
Dielectric absorption, which is also known as "soakage" and sometimes as "dielectric hysteresis"—is perhaps the least understood and potentially most damaging of various …

Capacitor Dielectric Absorption
Dielectric absorption is the inability of a capacitor to discharge completely to zero. This is sometimes called battery action or capacitor memory and occurs because the dielectric of the capacitor retains a charge.
