Electrical engineering is a broad and influential field that focuses on the study and application of electricity, electronics, and electromagnetism. It encompasses various sub-disciplines, each with its unique focus and applications. Here's an overview of the main areas within electrical engineering:

Power engineering involves the generation, transmission, distribution, and utilization of electric power. This area covers power generation through methods such as fossil fuels, nuclear, hydroelectric, and renewable sources like solar and wind. It also includes high-voltage power transmission from plants to substations and distribution to consumers, along with the design and maintenance of power grids, load forecasting, and reliability.

Electronics focuses on the behavior and movement of electrons in various devices and systems. Analog electronics deals with circuits that process analog signals, involving components like resistors, capacitors, and transistors. Digital electronics handles digital signals, including logic gates, microprocessors, and digital signal processors (DSPs). Consumer electronics involve devices such as smartphones, televisions, and computers.

Electrical engineering is a diverse and dynamic field that involves the study, design, and application of equipment, devices, and systems that use electricity, electronics, and electromagnetism. It encompasses a wide range of sub-disciplines, including power engineering, electronics, control systems, signal processing, and telecommunications.
