How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.

Chapter 5 Capacitance and Dielectrics
A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1). Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with
Is it healthier for a capacitor to be discharged to itself or to "ground"?
The only GUARANTEED safe answer is to discharge the capacitor, through a suitable resistor, across the capacitor terminals.. It is true that in most cases one side of the capacitor will be grounded and the other attached to some rail, HOWEVER this is NOT TRUE in all designs. There is no guarantee that grounding either pin of the capacitor to frame ground …
