Lab 3 – ELECTROSTATICS, I want you to do an individual report on Lab 3 – ELECTROSTATICS and I have provided the group report for information. Also do the expansion questions.

professor notes, please read them carefully. and please follow them.

” The conclusion section is for a quick summary of the data taken and observations made that help explain any results deduced from the experiment such as objective of lab or theories. Also the conclusion section includes principles demonstrated such as the relations that occurred during the experiment, things that are proportional so to speak.

Talk of errors is done in the analysis section of the report.

Please include a real life example and purpose an improvement to or for the lab. In the expansion section”

Lab 4: Electric Field Mapping

February 9, 2017
Theory/Procedure:

The purpose of this lab is to trace equipotential surfaces which will be used to map of electric fields produced by a potential difference. Lines of an electric field and equipotential surfaces are perpendicular to one another. The equipotential surface must be at right angles to the direction of the field at any point because electrical work is not required to move a charge over the surface. The apparatus and procedure were as follows: we filled a plastic box with some water and immersed a sheet of paper, we placed 2 hollow cylindrical objects on the paper and traced their positions with a pencil, we connected a power supply using clips to the metal and labeled the positive and negative ends on paper. We set the multi-meter to a 2-20 volt range and connected to the negative power supply, and the other end to a wire, then turned on the power to 10 volts. We set the probe in the water and read the multi-meter, marking the point, then moved the probe a few centimeters and marked another point that has the same potential, repeating this until enough points are available to draw an equipotential line. We performed this until we had 5 lines in order to determine a pattern map, then removed the paper to dry. We repeated this for additional object configurations: a large metal cylinder with a small metal cylinder inside, rectangular conductors, and a rectangular conductor and a small metal cylinder.

Data:

For the 2 metal cylinders, we found five lines at voltages of 2, 3, 4, 5.75, 7. For the two metal rectangular conductors, we recorded lines with voltages of 3, 4, 5, 6, 10. For the large metal cylinder with a small cylinder inside, we found lines for voltages of 2, 3, 4, 5, 6. For the rectangular and cylinder configuration, we recorded lines with voltages of 2, 3, 4, 5, 6. The data for these objects was submitted separately.

Summary Table:

The electric fields were predictable for us. For object one, the electric field around the cylinder was more rounded than the rectangular conductor due to the exaggeration of the potential lines. For object 2, the entire electric field was more rounded since there were two cylinders, and they cause more curves in the potential lines and field lines. For object 3, the field lines were more direct since the potential lines stayed straighter between the two rectangular conductors. For object 4, the field lines were straight lines to the outer cylinder since the entire map is a circle. Through the duration of this lab we discovered how the electric field lines intersect the potential line in a perpendicular fashion. When taking that into account, the potential lines become very important to find those specific locations.
