The resistance of the tungsten filament of an incandescent light bulb at 22 degC is 34 Ohms. If the light bulb is connected to a voltage of 126 V a current of 0.36 A flows through the filament. What will be the temperature of the light bulb filament under working conditions? The temperature coefficient of resistance of tungsten is 4.6E-3 1/degC. Your answer must be in degC, other scales are not accepted.
