Compute the temperature of the filament when the bulb is on

Reference no: EM13664242

A common flashlight bulb is rated at 0.30 Amp and 2.8 Volt (the values of the voltage and current under operating conditions). If the resistance of the bulb filament at room temperature (20°C) is 1.0 Ω, compute the temperature of the filament when the bulb is on? The filament is made of tungsten.
