What is a capacitor and how does it work?
What is a Capacitor? A capacitor is an electrical energy storage device made up of two plates that are as close to each other as possible without touching, which store energy in an electric field. They are usually two-terminal devices and their symbol represents the idea of two plates held closely together.
What is the working principle of a capacitor?
Working principle of capacitor: An insulated metal plate A is connected to an electrical machine [Fig. (a)]. Suppose, the potential of the plate is + V when it is fully charged. If C be the capacitance of the plate, the charge on the plate will be, Q = CV.
What is the construction of a capacitor?
