"Electronics is a branch of physics that deals with the study, development, and application of electronic components and devices. Electronics have changed our way of life and play an important role in the lives of human beings. From objects as small as a microprocessor to as large as a satellite, electronics have touched every sphere of life. Although most of electronic components are very small, they have important applications. The discovery of the electron marked the beginning of a new electronic era. The field of electronics is dependent on the phenomena associated with electrons and their properties. These phenomena and properties are exhibited by different electronic components. A few of the electronic components are diodes, triodes, capacitors, resistors, semiconductors, and so on. Thus, the importance of electronics in our daily lives should be realized in order to achieve further development. Hence, it can be rightly said that without the field of electronics the lives human beings lead would come to a standstill"--
