Electricity is the branch of physics and engineering that deals with the study of electrical phenomena and the behavior of currents and charges. It involves understanding how electric charges interact with each other and with magnetic fields, as well as the production, transmission, and use of electrical energy. Electricity is essential for powering various devices and systems, including lighting, telecommunications, computers, and household appliances. Researchers in this field study methods for generating electricity, improving energy efficiency, developing new materials and technologies for electrical systems, and exploring the potential applications of electricity in different industries.
