Example (PageIndex{1A}): Capacitance and Charge Stored in a Parallel-Plate Capacitor What is the capacitance of an empty parallel-plate capacitor with metal plates that each have an area of (1.00, m^2), separated by 1.00 mm? How much charge is stored in
The capacitance of a capacitor is the amount of charge that can be stored per unit voltage. The energy stored in a capacitor is proportional to the capacitance and the voltage. When it comes to electronics, the significant components that serve as the pillars in an electric circuit are resistors, inductors, 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}.
