The high damping capacitor voltage divider cannot be used as the load (wave modulation) capacitor of the impulse voltage generator. It is only used as a conversion device for measuring voltage.

As you know, a capacitor has two terminals, and we measure capacitors in terms of capacitance. Capacitance (C) is the ability of a capacitor to store energy. The unit of capacitance is Farad.
