[복사열전달] Radiation from light bulb

The incandescent light bulb is an object in which a thin metallic wire (filament) is surrounded by a transparent glass. Once the filament gets electrically heated, the visible light can be generated and emitted to the surroundings. Consider an incandescent light bulb with a filament (surface area: 10−5 m2 , emissivity: 1), and assume 150 W of electrical power is supplied and consumed by the filament. (a) Consider the filament as a blackbody, what is the corresponding temperature of the filament?...
