Calculate the energy radiated per minute from the filament of an incandescent lamp at 2000 K, if the surface area is 5 x 10^-5 m^2 and its relative emittance is 0.85.© BrainMass Inc. brainmass.com February 24, 2021, 2:12 pm ad1c9bdddf
We can consider the filament as a case of blackbody emission.
The energy radiated is given by,
E = A e $ t T^4
Step by step solution to the very interesting problem. The energy radiated per minute by a tungsten filament is examined.
