Electrical and Electronics is a field of engineering that focuses on the study and application of electricity, electronics, and electromagnetism. It encompasses a wide range of technologies, including circuits, transistors, and microcontrollers, which are essential for powering devices and systems in everyday life. This discipline is divided into two main areas: electrical engineering, which deals with large-scale electrical systems like power generation and transmission, and electronics engineering, which focuses on smaller electronic devices such as smartphones and computers. Together, they play a crucial role in modern technology and innovation.
