What Is the Structure and Type of a Capacitor, and Why Is It Essential in Electronics?

Among the countless components that make up electronic devices, the capacitor is a key element that cannot be excluded. What structure does this small part have, what role does it play, and why is it essential in all electronics? In this article, we’ll clearly explain the basic structure, types, and usage of capacitors.     1. Basic Structure of a Capacitor A capacitor basically consists of two conductor plates (electrodes) with an insulator (dielectric) sandwiched between them. Its main function is to provide capacitance , a space to store electric charge. When voltage is applied to the plates, one stores positive and the other negative charges, accumulating energy . 2. How a Capacitor Works Current does not flow through it, but the capacitor stores and discharges charges in response to voltage changes . Thanks to this characteristic, capacitors are used for voltage stabilization, filtering, and timing control in circuits.   ...
