A common flashlight bulb is rated at 0.300 A and 2.80 V (the values of the current and voltage under operating conditions). If the resistance of the bulb filament at room temperature (20°C) is 2.60 Ω, what is the temperature of the filament, in degrees Celcius (degC), when the bulb is on? The filament is made of tungsten.
