Block D Group 8 8.Question: How does light intensity affect electrical output of a PV cell 2.Hypothesis: If there is more intensity then the output of the PV Cell will increase. 3.Materials needed: Multimerter, aligator clips, 3 light bulbs (25w,75w,100w), foot candle meter, PV Cell, light stand.

4.Procedure: 1.hook the aligator clips to the PV Cel 2.keep the light 41cm from the PV Cell. 3.put the 25w bulb in and measure the intensity and the output of the PV Cell. 4.put the 75w bulb in and measure the intensity and the output of the PV Cell 5.put the 100w bulb in and measure the intensity and the output of the PV Cell 6.record all the data.

5. DATA TABLE! (Watts) ||
 * Light Bulb(s) || Intensity(Footcandle) || Output
 * 25 Watt Bulb || 130 || 5.12 ||
 * 75 Watt Bulb || 431 || 5.49 ||
 * 100 Watt Bulb || 694 || 5.73 ||

6. Graph paper.

7. Conclusion. In conclusion the data table shows that the more intense the lighting is the more electricity is produced.

8. Problems We had problems getting the correct results from the foot candle meter and electricity meter.
