Electronics engineering definition

Electrical Engineering and Electromagnetism
Electronics engineering is a critical field in engineering that focuses on the practical use of electricity. Electronics engineering is concerned with the practical use of the electromagnetic spectrum and the application of various devices, such as transistors and integrated circuits. The principles of electricity, electromagnetism, and electronics are applicable in numerous and solve everyday problems. Life would be unthinkable without the use of safe electric energy. The growing use of electricity is imperative for the rapid development of all fields and facets of human life. The rapid industrialization and modernization would not be possible if humanity lacked access to a steady supply of safe electric power. In this regard, electrical and electronics engineers play a critical role in enhancing the quality of life by engaging in research and consulting to come up with novel and safe ways of generating, transmitting, and enabling the use of electric power in the domestic, institutional, and industrial domains.
As advanced by Maxwells equations, the Theory of Electromagnetism establishes the fundamental principles that govern electronic and electrical circuits across the whole frequency continuum from optics to DC. Engineers understand that electromagnetics plays a central role in electronics engineering. In essence, electromagnetism focuses on fields and forces associated with charge. Accordingly, magnetism and electricity are the two components of electromagnetism (Walker, 2016). Three laws that define the electromagnetic theory are vital for research because they explain how the electric flux, the magnetic flux, and the magnetic fields operate in practical terms (Czarnywojtek,
