# Does capacitance change with frequency?

No, Capacitance does not change with frequency.

#### Explanation:

Capacitance of a capacitor is given as:
$C = \frac{Q}{V}$
It is simply the charge stored on the plates of a capacitor per unit voltage.

however, if you talk about the Capacitive Reactance ${X}_{c}$ of a circuit, it indeed depends upon the frequency.

Capacitive reactance is given as:
${X}_{c} = \frac{1}{2 \pi f C}$

Thus, it is the $C a p a c i t i v e$ $R e a c \tan c e$ and $N O T$ the $C a p a c i \tan c e$ which depends upon $F r e q u e n c y$.
