Electricity is a form of energy that results from the movement of electrons. It powers everything from lights and computers to cars and industrial machines. The basic principles of electricity involve understanding the flow of electric charge, which is measured in amperes, and how it travels through conductors like copper wires.
Ohm's law, which relates voltage, current, and resistance, is one of the foundational principles of electricity. Electrical circuits are designed to control the flow of current and make sure it is used efficiently. Advances in electrical engineering continue to improve technologies like batteries, motors, and renewable energy systems.
