A lgth century lab technician is testing possible metals for bulb filaments. A carbon filament with a surface area of 0.350 mm?2 and an emissivity of 0,977 radiates 2.20 W of light. Determine the filament's temperature (in K). The melting point for carbon is 3773 K. 2994 X Stefan's law provides a relationship between the power output P, the surface area A, the emissivity e, the temperature T (in K), and the constant = 5.67 x 10~8 W/(m?2 - K*). Be sure to convert the filament area from mm? to m2. K
