An electric kettle is a kitchen appliance designed to quickly heat water using electricity. It typically consists of a container, a heating element, and a lid. Most electric kettles have an automatic shut-off feature that activates when the water reaches boiling point, ensuring safety and energy efficiency. These kettles come in various sizes and materials, such as stainless steel, glass, or plastic. They are commonly used for making hot beverages like tea and coffee, as well as for cooking tasks that require boiling water, such as preparing instant noodles or oatmeal.
