Functional principles in capacitors
18.5: Capacitors
The capacitance of a particular capacitor is a measure of how much charge it can hold at given voltage and depends on the geometry of the capacitor as well as the material between the terminals. If too much charge is placed on a capacitor, the material between the two plates will break down, and a spark will usually damage the capacitor as well as …

How do supercapacitors work?
The capacitance of a capacitor increases as the area of the plates increases and as the distance between the plates decreases. In a nutshell, supercapacitors get their much bigger capacitance from a combination of plates with a bigger, effective surface area (because of their activated charcoal construction) and less distance between …

What is capacitor? Principle working, types and how it works
Case 1# The area of the plates parallel to each other. The capacitor has an area of plates very much. So it is the greater the capacitance. Case 2# If the distance between the plates is greater, it will reduce the capacitance. Case 3# Change the dielectric substance. Change the dielectric substance.

6.1.2: 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}.
