Generator Lab

For todays in class experiment/lab we got to genorate our own energy! One might as how does one do so? Here are the steps,

First Shake the tube at your desired  rate/speed

Second Count the number of shakes in the data collecting interval

Third calculate in excel the sum of the squares of the voltages (SSVs)

The steps were pretty stright foward, Lets begin the experiment shall me!

 We had 30 seconds to shake the generator tube as many times as we could keeping track of the number of shakes as we shook. This part I found a but challenging becuase shaking and counting proved to be a bit diffcult  for both myself and my partner. Hey what can I can say multitasking has never been on of my strong suites. HA

This is what our tube genorator looked like——–)

As we were shaking the genorator tube It reminded us alot of the shake weight, you know that chessy “exsercise” device that claims to tone up your arms. Come on admit it we’ve all see the informercials on TV!

My partner and I conducted 6 test. Here are our results for each time we shook the genrator.

First time 83 shakes (most times )

Second time: 0 shakes ( we did on purpose to see what would happen)

Third time: 53 shakes

Fourth time: 46 shakes

Fifth time: 34 shakes

Sixith and finial time: 47 times

The sum of the squares of the voltages:
First: 73.26246
Second: 99.51914
Third: 45.79768
Fourth: 64.46607
Fifth: 24.7404
Sixth: 73.25632

This is were my opps comes in, I believe that some were along while we were conducting the experiment we did a mistake because what SHOULD have happened(but didnt) was the tests with the greatest number of shakes would have the greatest SSVs. But accoring to our results thats not what happended.

 Second: 0 shakes                     Fifth: 24.7404
Fifth: 34 shakes                        Third: 45.79768
Fourth: 46 shakes                    Fourth: 64.46607
Sixth: 47 shakes                       Sixth: 73.25632
Third: 53 shakes                      First: 73.26246
First: 83 shakes                       Second: 99.51914

We’re not sure exactly what went wrong but if we had to guess it was probably be that our first run bulit up so much electcity that  most of it still remained in the next few seconds when we didn’t shake the tube at all. But we dont know this for sure. -_____-

All in all this lab was fun! (& it even allowed me to get my daily work-out in) ok just kiding i dont work out.HAHAH.  Even though our results didnt reflect the correct or suppose out come we still learned about Faraday’s Law which states that electricity or currents and voltage are generated by changing magnetic fluxes through coiled wires. So it wasnt a COMPLETE fail….I guess!

As always thanks for reading I’ll catch you on the next post!
