Capacitance is the amount of electric charge that can be stored in a capacitor or other device. It is called electrical capacity. The proportional relationship between the potential and actual amount of charge of a charged object can be described as follows: Q=CV[C] The proportionality constant C is the capacitance, and the unit is farads [F].
Capacitive reactance (X C, in Ω) is inversely proportional to the frequency (ω, in radians/sec, or f, in Hz) and capacitance (C, in Farads). Pure capacitance has a phase angle of -90° (voltage lags current with a phase angle of 90°).
