One end of the capacitor is connected to the power supply, and the other end is grounded, so what does this do?

Look at the location of this electricity, if in the power supply input and output section, generally known as the electric 1653 source input/output internal filter capacitor, used to stabilize the capacitance fixed output, beneficial to voltage regulation.
If it is near the amplifier power supply or integrated circuit power supply, the standard name of this capacitor is: decoupling capacitor.
It is generally used for power supply filtering to make the voltage added to (operational amplifier, semiconductor discrete amplifier circuit, power amplifier circuit) more stable.
There are generally two configurations of this capacitor: 1 is a relatively large capacitance of the electric power circuit, etc. Sometimes encounter precision integrated circuits, in the vicinity of its power supply can also see this design.
