The diameter of the tungsten filament of an electric lamp is 0.05 mm, and its length is 6 cm. When the lamp is connected to a network with a constant voltage of 110 V, a current of 0.55 flows through the filament. And what is the temperature of the lamp filament? Assume that in the steady state, all the heat released in the spiral is lost by radiation. The absorption capacity of tungsten is 0.31.
