An electric heater ( the only known 100% efficient device ).
The device that converts electrical energy to mechanical energy is an electric motor. Electric motors are also used as generators in hybrid automobiles to convert mechanical energy back to electrical energy.
A common electrical device that does not contain an electric motor is a toaster. Toasters operate using heating elements that generate heat to toast bread, without the need for a motor. Other examples include light bulbs and electric heaters, which also function through resistance and do not rely on mechanical movement.
