The tungsten filament of a certain 100 W light bulb radiates 3.00 W of light. (The other 97 W is carried away by convection and conduction.) The filament has surface area of 0.210 mm2 and an emissivity of 0.950. Find the filament's temperature. (The melting point of tungsten is 3683 K.)
The filament in a light bulb has a diameter of 0.02 mm and an emissivity of 1.0.
The temperature of the filament is 3×1000°C. What should be the length of the
filament in meters so it will radiate 60 W of power? The Stefan-Boltzmann
constant is 5.670 × 10-8 W/m2 · K4. Please give your answer with 3 decimal
places.
The tungsten filament of a light bulb has an operating temperature of about 2100 K.If the emitting area of the filament is 1 cm2, and its emissivity (ε) is 0.68, what is the power output of the light bulb?
