EE Science II Lab Charge Distributions and Electric Field Visualization in 3D 1. Summary: The laboratory assignment has 5 parts in order to complete it. Part I was about Theory – warm up. In this part of the lab, my partner and I had some theoretical questions to answer, which were related to the electric field and charge distribution. It was basic questions to help us start the lab experience. Part II was about Electric field of point charges. In this part of the lab, we had an electric charge of a particle with value of the charge, which were the position vector and its electric charge value that were graphed in table 1. Then, in the next step, we had to plug our group number to find the point or coordinates that the position vector laid on and as well as its electric charge value in table 2, which turned to be (3, 0) for the position vector, and 1x10^-3 for the Q value. To verify our answer for that, we had to run the matlab code that was given to calculate the particle A position and charge value. Next, it was a little matlab code, we had to generate the meshgrid and explained its purpose to the electric field. Last step, it was to compute the electric field by using the matlab code to see in the figure what the electric field in the charge distribution ooked like and write observation on it. Based on the figure, we conclude it by saying that the electric field is stronger as it’s closer to the origin and it directed to outside the charge distribution plus we explained the equipotential surfaces of that figure. Part III was about Electric field of a dipole. In this part, we had two different position particles with two charges and distance, so we computed the values for both position vectors A, B and charge values by the same process in part 1 with our group number. Then, we generated the matlab code to verify our answers which were correct. Last step in this part was plotting the values in matlab code to show the figure, which it indicated the B position vector had stronger electric fields than A position vector in the observation part. Part IV was about Linear charge distribution. In this part, we had to find the charge density and the length of the charged cylinder. We had to calculate both of them and then we run the matlab code to verify the answers. The process led us to plot the electric field by using the matlab code, plus we had to compare and plot the electric field for different values of l to see the difference of the electric fields in the charge distribution which displayed the electric field to have affect in the width as we increased l value. Part V was about Application of Electrostatics. In this part of the lab, we had a device that was composed of an ionized with a desolvation of gas chamber and a desolvation electrostatic lens. Therefore, for this part, it was to understand the process of the electrospray ionization and how we turned them into spray. Then, we found the polarities foe the nozzle as well as for the charge of the ionized protein molecules, and last thing, for the charge polarity on the lens. To sum up all this part, due to the high voltage, the N2 gas would deflect the particles away into the opining because of the sign of the charges around it and the droplets on the nozzle would make the charges to go all of them as in order of straight line, otherwise the charges would go in different direction away from the line. 2. Figures: A) Figure 1 page 5: For this figure above, the electric fields get stronger as they get close the origin and their direction are away pointing outward the charge distribution, also they have different equipotential surfaces and shape for every charge distribution on the figure but each equipotential has constant electric field. B) Figure 2 page 7: For this figure, we can see that we have two position vectors and the position in the left side which is B, has stronger electric field directed towards the charge distribution than A in the right side. Also, this figure has different equipotential surfaces in each one as we get closer we can see the strength of the electric field and the shape of it. C) Figures for l or L= 1 m, 11m, 21m, 31m: For these figures, we had to change the length for each figure and we found that as we increase L or l the figure gets wider and as well as the charge distribution at the origin. So, we can say that the electric field will increase with l and the position of the electric field will change for each length that we change or increase. Lastly for the equipotential, each figure will have different shape of each surface until the shaped to circle. 3. • • • • • Applications of electrostatics force on electrical engineering: Laser painters Photocopiers.

Charge Distributions and Electric Field Visualization in 3D
The main purpose of the lab was to investigate the distribution of charges as well as to
visualize the electric field in 3D. The lab involved performing several computations related to
electric field. The lab was conducted in five different parts. Part I of the lab (warm up) involved
answering some theoretical questions regarding charge distribution and the electric field. Part I
was essential in establishing a background context for the other parts of the lab. Part II of the lab
involved investigating the electric field created by point charges. Precisely, we used MATLAB
to determine the electric field due to particle A. first, we calc...
