Electricity is the flow of charged particles, primarily electrons. It's a fundamental force that powers our world. Key components include electric charge, current, voltage, and resistance. A circuit consists of a source, conductor, load, and switch. Ohm's Law relates these components: V = IR. Electricity comes in direct current (DC) and alternating current (AC) forms. #electricity #physics #science #engineering #technology #electronics #electrical #circuit #power #energy
