$begingroup$ To add to this answer, the way good capacitance meters measure capacitance is by applying a small (generally 30 mV peak) AC voltage and measuring the resulting current. This gives you an impedance, and that''s then converted to capacitance that''s displayed on the screen. Good LCR meters will also separate out the …
Capacitor and Capacitance

Introduction to Capacitors, Capacitance and Charge
The parallel plate capacitor is the simplest form of capacitor. It can be constructed using two metal or metallised foil plates at a distance parallel to each other, with its capacitance value in Farads, being fixed by the surface area of the conductive plates and the distance of separation between them.

Capacitors and Capacitance: Introduction, Types, Properties
What is a Capacitor? Capacitors are also known as Electric-condensers. A capacitor is a two-terminal electric component. It has the ability or capacity to store energy in the form of electric charge.Capacitors are usually designed to enhance and increase the effect of capacitance.Therefore, they take into account properties like size and shape.
8.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
