Electric current is an electrical phenomenon caused by the movement of electrons from one point to another. Electricity is essentially caused by the movement of charged particles, usually electrons. This current refers to the flow of charged particles travelling in a certain direction in a circuit.
Basic Concepts of Electric Current:
Electron Motion:
Electric current is caused by the movement of electrons from one point to another. When electrons are passed through an energy source (usually a battery or generator) in a circuit, a current flows through the circuit.
Amps and Units:
Electric current is measured in amperes (A). One ampere represents electric current carrying one coulomb of electric charge in one second.
Direct Current (DC) and Alternating Current (AC):
Electric current exists in two basic types, direct current (DC) or alternating current (AC). Direct current is a current in which electrons move in a single direction, but alternating current is a current that periodically changes direction.
