Block C Group 6 1. Question: How does the distance from a light source affect the electrical output of a PV cell? 2. Hypothesis: If the PV cell is further away from the light source, Then the electrical output would be less. 3. 4.
 * One meter stick
 * one 100W incandescent bulb
 * One multimeter
 * Two alligator clips
 * 1) Lay the meter stick down and put 100W incandescent bulb at the end of the meter stick.
 * 2) Attack multimeter cell to the solar cell.
 * 3) Plug the light in.
 * 4) Hold the solar panel at a 90 degree angle at every interval.
 * 5) Start at 10 and procdues in 10 cm intervales and record the volts in the data table.
 * 6) Clean up material and put away.
 * 7) Graph your results and write your conclusion.

6. Graph: See paper. 7. Conclusion: 8.
 * Our hypothesis was correct. When the PV cell was moved away from the light source, the voltage lessened.
 * If you used a PV cell at home for energy, you would have to make sure the panel was always facing the sun and was a relatively good distance to take in the energy.
 * Keep the solar panel at a 90 degree angle.
 * Taping the solar panel to a book.
 * We would start father away.
