Our group consisted of Jersson, Amy, Cisnell, Stefanie, and Matt Crane. The presentation went pretty well overall. However, our generator, Alto, was a damaged a little bit when we passed it around but it was not a big deal. Our group was assigned to explain and show our experiment with another group who did one of the experiments Tom Vale showed us.
The other group’s experiment was interesting. They did calculations to see how many RPM’s the motor was running at by adding a dot on the wooden shaft. By adding or removing filters they could either slow down or speed up the motor. By moving the distance of the light closer or farther from the solar panels also increases or decreases the speed of the rotation. Moving the light closer increases the rotation, moving it farther away decreases it.
Our generator worked well. it produced 25 milliamps and .06 mV. For being built out of cardboard and getting all of the supplies from radioshack, it is pretty amazing what a person can build. Generator’s like this one can help the people in countries that do not have consistent power. Obviously, the bigger the crank generator is the more it can power. Also, the better materials that are used the more voltage that can be produced. In conclusion, we were able to accurately calculate measure the voltage output. Below is our write out of the experiment.
Everyone put into this experiment. Cisnell and Stefanie made the write up and power point look good. Jersson, Amy, and I worked on creating the generator. The group had no problems and worked well together.
