This past week, we worked on a manual flashlight experiment, where we manually charged a flashlight. The flashlight had a copper coil inside which conducted the electrical charge throughout the experiment. There was also a magnet on the inside of the flashlight that would slide to opposite sides of the flashlight whenever we would shake it. This movement of the battery helped create the charge, while the copper coil conducted the charge. This was hooked up to the computer, so that we could accurately get our results. Over the course of the three trials, these are the results below.
Baseline: 0 shakes; sum squared: 0.292718
Even though we were not actually shaking the shake light, there are still some charges flowing through the light, so there is still a charge even though nothing is actively going on.
Trial 1: 44 shakes; sum squared: 245.8468
Trail 2: 23 shakes; sum squared: 100.1544
Trial 3: 16 shakes; sum squared: 40.15929
Looking at the above data, it is easy to see that the more shakes, the greater the charge and the greater the sum squared (of all the numbers that the light generates and then square it) will be. Below is a scatter plot chart of our results.
