An understanding of the basic principles involved in this concept of "Insulation Resistance" should help to dispel this confusion. When a capacitor is charged from a DC energy source, an initial high current flows from the energy source into the capacitor. This current flow rapidly decreases toward zero as the capacitor absorbs it.
