A GE Softwhite lightbulb is rated as follows:
The resistance of the filament of the bulb, measured with a standard multimeter is 16.7 ohms. When the bulb is connected into a circuit and is operating at the rated values given above, determine the resistance of the filament and efficiency of the bulb.
***answer should be 220.4 ohms and 2.009%*** I didn't get the same answer...
The solution involves step-by-step calculations and explanation for finding the resistance of the filament and efficiency of a light bulb.
