In short, the little chisel becomes in his fingers a painters brush, and when it is remembered that, the basis upon which he works being simply a thread of silk, his hand must be trained to such delicacy of muscular effort as to be capable of arresting the edge of the knile at varying depths within the diameter of the tiny filament, the difficulty of the achievement will be understood. The filament of an electric lamp is very fine and therefore offers considerable resistance. The filament can be instantly burned out by passing a current of too high pressure through it. It is dependent on the nature of the material, its thickness and length, and on temperature. The filament bulb is just one of many examples were energy is transferred usefully, BUT there is always heat energy lost to the thermal energy store of the device and the surroundings.
