What is the difference between the way we can get an electric stove and a cellphone to work?

An electric stove operates by connecting to a power source, allowing electricity to flow through heating elements, which generate heat for cooking. In contrast, a cellphone works by utilizing a rechargeable battery that powers its internal circuits, enabling wireless communication and various functions. While both devices rely on electricity, the stove directly converts electrical energy into heat, whereas the cellphone uses electrical energy to power electronic components and facilitate connectivity.
