Web100 hours, this again is due to the capacitor construction. The supercapacitor can be modeled as several capacitors connected in parallel each with an increasing value of series resistance. The capacitors with low values of series resistance charge quickly thus increasing the terminal voltage to the same level as the charge voltage. WebWhen the leakage is very low such as in film or foil type capacitors it is generally referred to as “insulation resistance” ( R p ) and can be expressed as a high value resistance in parallel with the capacitor as shown. When the leakage current is high as in electrolytic’s it is referred to as a “leakage current” as electrons flow directly through the electrolyte.
