So that the hold kettle place will be not hot
so that we can hold them to pour in a cup to drink
An electric kettle is made up of metal so that it is able to conduct heat to ensure the liquid inside the kettle absorbs heat and boils whereas the handle is made up of non-metal which acts as heat insulator. Heat insulator is unable to conduct heat. As the handle is heat insulator we can easily carry the kettle by its handle. This is also safe.
