An incandescent light bulb has a tungsten filament that is heated to a temperature of 3.20 × 103 K when an electric current passes through it. If the surface area of the filament is approximately 1.00 × 10−4 m2 and it has an emissivity of 0.360, what is the power radiated by the bulb?The Stefan–Boltzmann constant (σ) is 5.670 × 10−8 W/(m2·K4).
