Capacitance and Charge on a Capacitors Plates
Capacitance and Charge on a Capacitors Plates
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}.
Are capacity and capacitance the same?
If by "capacity" you mean the amount of net charge on the plates, then obviously that''s not the same as the capacitance of the capacitor which is the charge divided by the voltage. The capacitance of a capacitor is greater if the work required per unit charge to separate the charge on the plates (i.e., the voltage) is less.
Capacitors
If two initially uncharged capacitors of capacitance C 1 and C 2 are connected in series to an input voltage V, then each capacitor must carry the same opposite charges on its plates, regardless of the values of C 1 and C 2 .

Capacitance Formulas, Definition, Derivation
When capacitors are connected in series, the total capacitance (C Total) is less than any individual capacitance (C 1, C 2, etc) due to the reduced effective area for charge storage. The reciprocal of the total capacitance is the sum of the reciprocals of the individual capacitances:
