One plate is grounded when the capacitor is charging

Introduction to Capacitors – Capacitance The capacitance of a parallel plate capacitor is proportional to the area, A in metres 2 of the smallest of the two plates and inversely proportional to the distance or separation, d (i.e. the dielectric thickness) given in metres between these two conductive plates. ...

Is it healthier for a capacitor to be discharged to itself or to "ground"?

To discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. Whether there is also a connection to some "ground" makes no difference to the process. What you might be seeing is that in a specific circuit, one terminal of the capacitor is already connected to ground (or any other bus / …

The unit of capacitance is the farad (F), named for Michael Faraday (1791–1867), an English scientist who contributed to the fields of electromagnetism and electrochemistry. Since capacitance is charge per unit voltage, we see that a farad is a coulomb per volt, or

Physics A level revision resource: Introduction to capacitors

Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.
