The tungsten filament of an electric lamp has a surface areaA and a power rating P. If the emissivity of the filament is varepsilon and sigma is Stefan's constant,the steady temperature of the filament will be:

The tungsten filamet of an electric lamp, has a length of 0.25 m and a diameter of 6xx10^(-5) m. The power rating of the filament is 0.8, estimate the steady temperature of filament. Stefan's constant =5.67xx10^(-8) W//m^(-2)//K^(4) .
