How electricity flows through metals
Most of the electricity we use every day is conducted from its source through metal wires to the appliances we use. Most metals, such as copper, conduct electricity well because they possess a great number of free electrons. An electronA subatomic particle that orbits the nucleus of an atom. It has a single electrical charge. is an extremely small particle with a single electrical charge that orbits the nucleus of an atom. Materials with few or no free electrons do not conduct electricity and are called insulatorsA material through which little or no electrical current will flow.. They are commonly used to coat the wiring we use, allowing the electric current to flow safely and efficiently through the wire.
The flow of electrons in an electric current...
