Understanding Other capacitors are electronic components that can store and discharge electrical charges. The structure of a capacitor is made of 2 pieces metal plates separated by a dielectric material [10]. Common dielectric materials are vacuum air, ceramics, glass and others. If both ends of a metal plate are given an electrical voltage, then a positive charge will accumulate on one of the metal legs (electrodes) and at the same time the negative charges will accumulate on](https://www.researchgate.net/publication/387961002/figure/fig1/AS:11431281303177220@1736770505073/Sequence-of-color-rings-on-resistors-7-242-Capacitor-A-capacitor-is-an-electronic_Q320.jpg)

Moving on from the discovery of diodes, experts also found other unique derivative components. Diodes have a unique function, which is that they can only conduct current in one direction. The diode structure is nothing but the connection of the P and N semiconductors. One side is a semiconductor with type P and the other side is type N. With such a structure, the current will only be able to flow from the P side to the N side [11].](https://www.researchgate.net/publication/387961002/figure/fig2/AS:11431281303168656@1736770505210/Basic-Principles-of-Capacitors-7-243-Diode-Diodes-are-electronic-components-made-of_Q320.jpg)

Transistors can also function as electrical faucets, where based on their input current (BJT) or input voltage (FET), allows for a very accurate flow of electricity from their power source circuits. The transistor functions as a switch. By controlling the bias of the transistor until this component becomes saturated, it will cause as if a short connection is obtained between the emitter and the collector leg. This phenomenon can be used so that transistors can be used as electronic switches. The function of the transistor as a current amplifier.

The development of information technology has had a positive impact on the world of education, one of which is to simplify the learning process. In the field of electronics, understanding basic components is an important foundation for students and practitioners. This Java Desktop-based application design aims to introduce basic electronic components with an easy-to-understand interactive interface. In this software, it contains various information about basic electronic components such as Resistors, Capacitors, Transistors, Diodes, Push Buttons, which is equipped with detailed information about the specifications and basic functions of various electronic components. In addition, the app comes with visual illustrations in the form of images that support the understanding of physical and component symbols. To explain how components in a series work, the app presents interactive animations to clarify the concept of how each component works and functions. During the creation and testing of 5 times, which was carried out using 5 different basic components resulting in different circuits and explanations of how to work, these results then obtained data from these 5 components which were then entered into the MySQL Database. The data present in the Driver Database is displayed using the Desktop-Based Java Programming Language.
