Question: A 19th 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

A 19th 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. o) 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 108 W,/(I'n2 . K4). Be sure to convert the filament area from mmZ2 to m2. K
