Resistors and Ohm's Law: The World of Circuitry

June 25, 2012 - 3rd Meeting of Physics 102.1 Lab

Today, as I would say the least, is the day of transition from the observation of the behavior of charges and electric fields, to the manipulation of electric circuits. Looking at the materials we used to establish the  experiment, I felt a little bit dazed constructing the set-up. From the least possible sizes of color-coded resistors, to the hazardous structure of a power supply, we conjured a set-up best fit for the experiment. 

From start until the end, we enjoyed recording the data, knowing that some of it may have become irrelevant and incongruous to the objective of the experiment. Moreover, the fun started when we conducted the experiment concerning the German nickel wire, of which is the first set-up to use a big power supply. Me and my teammates handled the succeeding experiments well, constructed with enough materials to propagate enough data that would generalize our objectives.

Throughout the whole experiment, I was a bit oblivious of the whole aspect, but then I realized that I am a physics major who would, in any consequences, evolve and adapt to several admissions, and finish a job with polished information.

Equipotential Lines and Electric Field Lines

June 18, 2012 - 2nd Meeting of Physics 102.1 Lab

It's been a while since I've done experiments in a physics lab. From mechanics and kinematics, we are to examine the world of electricity and electromagnetism. Our whole physics 102.1 lab journey starts with tracing electric fields through equipotential lines. 

The equipment are new, the style of gathering data is new, and the way we conducted the experiment is surprisingly new. We are to trace equipotential lines in an electrolytic tank where two different electrodes are placed. The set-up is rather confusing, and judging from the way the coordinate system is configured, we are caught up in an array of disastrous coordinates. We started the experiment slowly, but as we figured out the way we would approach the experiment, a swift wind blew throughout our process. We managed to finish the data gathering, although inconsistencies are still seen. 

After the experiment, we are to produce a technical report summarizing the data we gathered.
