Electrical wire is a conductor used to carry electricity from one point to another. It is typically made of materials like copper or aluminum, which allow electric current to flow easily. The wire is often insulated with plastic or rubber to prevent accidental shocks and short circuits. Electrical wires come in various sizes and types, each designed for specific applications. For example, household wiring is usually thicker to handle higher currents, while electronic devices may use thinner wires. Proper selection and installation of electrical wire are crucial for safety and efficiency in any electrical system.
