Generator Activity

In class for our robotics experiment we made and experimented with a generator. As stated in the generator lab description Fraday’s Law is the changing of magnetic fluxes through coiled wires which generates electricity currents and voltages. Therfore, the more or greater the change in magnetic flux the more or higher the currents and voltages will be. In this lab, the higher our shakes the higher the voltage that will be generated.

Before I moved to Boston, I grew up in New Hampshire. While living in New Hampshire there were many times, for example, the ice storm we had in 2008 that completely wiped out our electricity for weeks. During this time my family thankfully had a generator which made it so much more livable. At the time I didn’t try to figure out how the generator worked I just thought it was amazing because it could generate heat, and electricity, that is why this lab was interesting to see how the generator actually worked.  

In this lab we as a group shook our mini ‘generator’ four times, the first time we shook it zero times and surprisingly there was slight voltage, and the second time we shook it 22 times, the third 40 times, and the fourth 60 times. The sum of the square of voltages is then found which is also considered as polarity. Below is a simple visual of how a generator works, and the spinning can represent the shaking that we did in our experiment.

Every time that we shook the generator more the voltage would go up, which meant that more electricty was being produced. If you think about it sense the magnet fluxing through the coiled wires generates electricity the more that the magnet touches the coiled wire the more electricity will be made, that is why the faster and longer that the ‘generator’ was shaken the generator which was also a flashlight would start to work as an actual flashlight, it created electricity.  Our Sum of Square Voltage graph is a great visual in showing how the more shakes the more electricity.

The results that we came up with after shaking the generator four times are stated below along with our graph:

    You did a good job explaining how we did the experiment. I also liked how you gave a personal touch as to how generators can benefit our everyday lives.

    By relating our labs to everyday and our personal experiences, it makes each blog more appealing and I think you diverged the two in an excellent way. Although you have a personal experience, you still do a great job explaining our lesson.
