"My science fair project was about how solar cells output different voltages depending on the light intensity. I was using a solar cell, a clamp-on-lamp, different wattage light bulbs and a multimeter to give out the results, which was true that the different light intensities do in fact affect solar cells output. However, the last bulb, the 150 watts bulb, did somehow detach the wire from one of the two filaments, so the result that the graph showed would possibly be a little off from the others."
