Introduction

Electrical engineering is an engineering discipline that involves the research, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. In the second half of the 19th century, with the commercialization of the telegraph, the telephone, and the generation, distribution, and use of energy, it became an identifiable profession.

Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, energy engineering, telecommunications, radio frequency engineering, signal processing, instrumentation, electronics, optics, and photonics. Many of these disciplines overlap with other branches of engineering and span a large number of specialties, including hardware engineering, power electronics, electromagnetism and waves, microwave engineering, nanotechnology, electrochemistry, renewable energy, mechatronics, and materials science.

What Is Electrical Engineering?

Electrical engineering is among the most modern areas of engineering, dating back to the late 19th century. It is the branch of engineering that deals with electrical technology. Electrical engineers work on a broad variety of components, devices, and systems, ranging from small microchips to massive power plant turbines.

The original battery and electrostatic charge were used in the first electrical experiments. On the other hand, the actual design, construction, and fabrication of actual devices and systems begin with the application of Michael Faraday’s law of induction, which states that the voltage in the circuit is proportional to the rate of change of the magnetic field. Cross country circuit. This rule governs the basic principles of electric generators, electric motors, and transformers. The introduction of electricity into homes, businesses, and industries herald the arrival of the modern era, all of which are carried out by electrical engineers.

Thomas Edison (electric light bulb), George Westinghouse (alternating current), Nikola Tesla (induction motor), Guglielmo Marconi (radio), and Philo T. Farnsworth (television) are some of the most notable electrical engineering pioneers. These pioneers transformed electrical theories and concepts into practical devices and systems that ushered in the modern era.

Electrical engineering has evolved and branched out into numerous specialised areas since its early origins, including power generation and transmission systems, motors, batteries, and control systems. Electrical engineering also covers electronics, which has further subdivided into radio frequency (RF) systems, telecommunications, remote sensing, signal processing, digital circuits, instrumentation, audio, video, and optoelectronics.
