Generator Experiment

During our last class my partner and I experimented with a generator/flashlight that stored energy and powered up by shaking it. After we connected the generator to the computer, we shook it a few times for 30 seconds each time alternating the speed and therefore the number of shakes. We counted the number of shakes, recorded the voltages and calculated the sum of the squares. We found that the faster we shook and the greater the number of shakes the greater energy produced to power the generator. We then plugged our number into an excel sheet and graphed it.

Our results:

# of shakes Sum of the square of voltages
16 73.69535385
18 73.69478741
32 113.0244935
62 98.94199537
145 97.64672989
