Capacitor on power supply
$begingroup$ @Fed if you have a big discharged capacitor, a switch and a power supply in a mesh, once you close the switch, the instantaneous current will be V/R, where V is the power supply voltage and R is the parasitic + initial contact resistance. R could be very small, therefore the current and instantaneous power will be very large. Therefore you need more …
What is Capacitor and How Does It Work ?
Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.

The Fundamentals of Capacitors in AC Circuits
However, the charge is returned to the power supply when one is positive, and the other is negative. No power is consumed because the charge is the same size as the discharge. There is as much power curve above the zero line as below it. The average power in a purely capacitive circuit is zero. Takeaways of Capacitors in AC Circuits
