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 |
