 Project Title:

  Investigation of the effect of temperature on the brightness of the light bulbs.


 Type of Project:
  Measure a function or relationship: Experimental research (II)



Abstract:



In daily life, it is observed that with usage light bulbs heat up leading to a rise in temperature.The purpose of our experiment was to find if the brightness of the light bulb is affected by the rise in temperature for up to 3 hours of continuous usage. We conducted the study of three types of light bulbs; filament, fluorescent and LED. Our results indicated that there was no change in brightness of all the three types of light bulbs with increase in temperature due to the heating effect. The increase in temperature was small and in the lower range of temperature and hence did not cause any change in the brightness. These results helped to remove the misconception among students that the heating effect of the bulbs would affect its brightness.
