The coil of wire in an electric room heater or electric cooking heater is called _______.
Element
The heat-producing coil in an electric room or cooking heater is called the heating element. It is made of a high-resistance alloy (typically nichrome) wound into a coil; current through it generates heat via Joule heating, \(H = I^2 R t\).
A “filament” refers to the thin wire in incandescent bulbs (designed to glow as light), while a “circuit” is the whole current path and “cells” are energy sources, not heaters.
