The fourth experiment using Lego robot was to generate voltage by shaking the generator by hand! Voltage can be described as the electric potential difference between two points; another name for voltage is (Electric potential difference).  It was very interesting lab to actually see how a single person can generate voltage just by applying force on the object. For example, People can generate electricity just by biking; this force will transfer to get an electricity output from it. Moreover, the primary purpose of this experiment was to see how voltage can be produced by people’s energy and the fun part is to see which group in class are the strongest to produce more voltage.

In this experiment my partner and I have set all the equipments and the programs that will be calculating our voltage output. First we were assigned to do the experiment five times and notice the difference between them when changing the numbers of shakes. Knowing that it will be tiring to do (Ha ha!) Noor (My partner) decided that we should take turns so we can have fun and be tired equally. We had a long talk about the last turn, nobody wants to do it. The second assignment was to add in all the data to excel and show the slop of the number of shakes versus the output voltage.

Data and Graph:

 Figure 1:

In figure one, it shows the number of shakes that were generated by my partner and I, the output voltage data calculated by Matlab, and finally the sum of all the output voltage From the graph we can notice that when there were no shakes on the generator there was barley an output voltage, but by the time we increased the number of shakes the output voltage increases tremendously, depending also how strong you are! This relationship is directly proportional.

Figure two: (Two pats):

In figure two, it shows us the relationship between the numbers of shake and the sum of the voltage for each shake column.
