1. Question- How does the angle of a Photovalic Cell affect the electrical output?

2. Hypothesis- If the angle of the Photovalic cell changes, then the energy gathered will decrease or increase.

3. Materials -2 Alligator clips -100 watt Incandecent Light Bulb -1 Dome Lamp -Protractor - Photovalic cell - Meter stick - Multimeter - Ring stand 4.Procedure
 * 1) Gather Materials
 * 2) Attach Alligator clips to diodes on the PV cell
 * 3) Attach Clips to multimeter
 * 4) Measure height of bulb from PV cell (Should be 30cm)
 * 5) PV set flat at 0 Degrees and turn on light for 20 seconds and record
 * 6) Record the voltage every 20 seconds After Tilting the PV cell up 10 degrees every 20 seconds

5.Data Table


 * = Degree ||= Electrical Output (Voltage) ||
 * = 0 ||= 2.53 ||
 * = 10 ||= 5.42 ||
 * = 20 ||= 5.60 ||
 * = 30 ||= 5.64 ||
 * = 40 ||= 5.61 ||
 * = 50 ||= 5.59 ||
 * = 60 ||= 5.54 ||

7.Conclusion As the angle changed, the energy taken decreased

8.Problems Accuracy in the timer and the light starting and stopping at the same time
