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. When plugged in, the heating element warms the water until it reaches boiling point, making it ideal for preparing tea, coffee, or instant meals. Most electric kettles have an automatic shut-off feature that turns off the kettle once the water has boiled, ensuring safety and energy efficiency. They come in various sizes and materials, such as stainless steel or glass, and often include features like temperature control and keep-warm functions for added convenience.
