The experiment last
week was kind of a challenge. Not knowing much about the experiment or about
electric field lines and equipotentials is kind of a disadvantage. Our group
had a difficulty finding the electric field lines and actually what we are
doing is wrong. But before I go to those details I’ll introduce our activity
first.
The Title of the
experiment is “Electric Potential and Electric Field”. What we are to do is to
know and graph the equipotentials and electric fields of 3 set-ups: a) 2 metal
disk, b) 2 line charges and c) one metal disk and one line charge. The general
set-up consists of an electrolytic tank, probes, conductors, DC voltmeter and
the charges.
Using the probes and
the DC Voltmeter we looked for spots where the reading will be 0 to be able to
graph the equipotentials. Unfortunately, all the way throughout the experiment
we did just that. We run the probe around the electrolytic tank searching for
zero-reading points. Well, it was partly correct however that should’nt have
been the bulk of the experiment. We should’ve been looking for voltmeter readings
which grow larger or smaller every other electric field line. For example:
Line charge and metal disk
As you can see, each electric field gives a different reading.
The reading should
differ from one field line to another.
Basically that’s what
we did in the experiment. Searching, gathering data, plotting points, graphing.
With these, we answered the questions and finished the paper. For more of the graphs.
