Estimate the temperature of filament when the bulb is on

Reference no: EM13668474

A common flashlight bulb is rated at 0.30 Amp and 2.8 Volt (the values of the current and voltage under operating conditions). If the resistance of the bulb filament at room temperature (20 degree Celsius) is 1.1 ohm, Estimate the temperature of filament when the bulb is on? The filament is made of tungsten.
