Generator Experiment

Creating Voltage 

In this experiment we used the following objects; one generator, (magnet that moves back and forth inside a coil of wire), one voltage probe (to measure voltage), one NXT adaptor, Labview VI and an excel sheet to organize all of our data into a scatter graph.

The point of this lab is to show how to create electricity, by shaking the flashlight. If you don’t shake it, would not create any voltage. The flashlight has wires attached that are sticking out, and we connect it to the voltage probe, that is connected to the NXT and the NXT is connected to the computer with an usb cord. The more the magnetic feels the more electricity we created.

First we start by using the LabView program, it waits one second to take a data. For 30 seconds it will record a voltage.

We shack the flashlight, and the voltages are automatically recorded in the Labview file and in the excel file.  We do this 4 times and once we start shaking it we start creating energy, we have to keep track of how many times we shack it. However, some voltages are negative and some are positive, and that depends on the magnetic energy whether it decreases or increases.

We first shacked it 32 times and it created 12 voltages. Then, we shacked it 35 times and it created 77 voltages. The third time we shacked it 46 time and it created 89 voltages and the fourth time we shacked it 98 times at a really fast speed and it created a number of 80 voltages.

We record the amount of voltages made in the excel sheet. We added all of the numbers and then we squared all the voltages in the excel file and then we sum them up and that gave us an idea of how much electricity we created.

    The scatter graph shows that the more shakes the greater voltages are. The x axis shows the number of shakes, and the y axis shows the voltage made.  The line illustrates the more of number of shakes the greater we can see it increases.
