Why Use a Capacitor?
Store energy temporarily
Filter noise from signals
Smooth voltage in power supplies
Create time delays (in RC circuits)
There are other uses for a capacitor, but they are rarely used.
As you can see, a capacitor is connected in parallel between the input and GND of the components it is meant to affect.
