Introduction
An open coil heater is an electric heating element consisting of a metal wire coil, usually made from materials like nichrome or kanthal. The coil is exposed, meaning it isn't enclosed in a protective casing. When electricity flows through the coil, it heats up due to the wire's resistance, generating warmth. This heat is then transferred to the surrounding air or objects, making open coil heaters effective for warming spaces or surfaces. They are often used in space heaters, toasters, and some industrial processes.
