What is Bypass Capacitor : Types, Functions and its Applications
A capacitor is a device that can be used to store electric energy. It has two terminals and its effect is called capacitance. A capacitor basically consists of two metal plates that act as a conductor with a dielectric medium in between. The conductor may be in the form of electrodes or metal plates or thin foil. ...

A bypass capacitor, also known as a decoupling capacitor, is an electronic component that is used to reduce noise and stabilize the power supply voltage in electronic circuits. It is connected in parallel with the power supply and the ground, close to the device or integrated circuit (IC) that it is meant to protect.
