If the charge stored on a capacitor is plotted as a function of voltage then we expect a linear relationship. Note: Don''t get Capacitance (C) and the unit of charge - Coulombs (C) - mixed up! E.g. The charge stored on a 1000 µF capacitor charged to 12 V is: Q = C × V = 1000 × 10-6 × 12 = 0.012 C. If the charging current were 10 mA then this would take 1.2 …

Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor. In fact, this is true not only for a parallel-plate capacitor, but for all capacitors: The capacitance is independent of Q or V.If the charge changes, the potential changes correspondingly so …

The *omega* is a representation of the frequency that is being applied to the circuit and the ''c'' is the measured capacitance of the capacitor. As these terms are in the denominator, we can see that if you increase either the frequency or the capacitance, the impedance of the capacitor decreases. If the frequency is 0, the impedance will be ...

Capacitors Basics
The capacitance of a capacitor is measured in a unit called the farad. Now, a farad is a pretty big unit, so capacitors used in everyday electronics are usually measured in microfarads (µF), nanofarads (nF), or even picofarads (pF). These smaller units represent a fraction or multiple of a farad, depending on the size of the capacitor.
