Cover Memo
The outcome of my electrical project was a terrific outcome. I managed to work out my schedule to efficiently and effectively complete the circuit. My first mission was to come up with a legitimate set of calculation which would allow me to meet my criteria for the project. After successfully coming up with calculations, this subsequently led to me beginning to build my circuit. Building the circuit became a challenge because I had to remember to align my voltage drops with the correct resistors. Overall, the project was a success! Without the correct use of mathematics, this project would not have been possible. Math enables solutions to problematic equations. With that said, the circuit board was an overall problematic equation that needed to be solved through mathematics. In order to fully understand the relevance of these mathematics problems, I must first had to be aware of the different rules with creating on electrical circuit board; rules such as Ohms Law and well as Kirchhoff’s Law. Being able to discern the proper use of series and parallel calculations played a pivotal role in completing this assignment. In the following sections, I will further elaborate on the pros and cons of the electrical project.
Abstract/Summary
The purpose of this project was to apply the engineering design process to an electrical circuit problem. From writing the first basic problem statement to the submitting the final laboratory report, this project was able to challenge my ability to use the various tools acquired throughout the semester. These tools ranged from time management, attention to detail, simple mathematical calculations and calculation accuracy. In addition to constructing and testing a direct current (DC) vol...

...f my actual voltage of 2,506.666. After identifying my possible series, I can begin to complete my calculations. Node 3 was a complicated circuit. This set required 3 resistors in a parallel set as well as a series set. My goal was to get within 5% of 5,911.88. My calculations were1/((1/220)+(1/220)+(1/220) )+330+3,300+2,200. My last two nodes took the longest time because at this point I was limited on resistors. In order to make this circuit successful, I made to sets of parallel sets; each parallel set had 3 resistors each. This left me with enough resistors to complete the rest of the board without exceeding my limit. My project was a success and if it had not been for my sources, this would have been more complicated. My only recommendations is to better explain and simplify Kirchhoff’s Law so that the student can succeed without too self-teaching references.
It was also possible to simulate ED system after the electric resistances of the equivalent circuit were obtained from the analysis of the time course of PaCl. The simulation results agreed with ED data very well.
In procedure A, one must know what an electrolytes is, which is a substance that produces an electrically conducting solution when dissolved in a polar solvent, in this case water is the solvent. Based on the results of the experiment it is can be concluded that the sodium chloride solution best conduct electricity. This is due part by ions being separated into Na+ and Cl- ions from the original NaCl. In other words NaCl(s) becomes Na+ (aq) + Cl- (aq). In doing so allows electricity to flow in the solution. As for the pure/distilled water not conducting electricity it is because it is very filtered free of minerals. Essentially, distilled water lack ions to efficiently conduct electricity, this also applies to the pure substance of sodium chloride and sucrose which lack ions, atoms that have a net negative or positive charge. However, according the results the sucrose is slightly conductive, which may suggest a possible contamination in the solution. At the end it can be reasoned that because ions were made in the NaCl solution, ions contribute to the conductivity.
Before any chemical reactions occurred, there was 0.46 grams of elemental copper metal. After the copper was added to the 250 milliliter beaker containing the 5.0 milliliters of nitric acid, nitrogen dioxide gas came out. The gas color was a light brown color, and the clear nitric acid within the beaker became a green-brown color. Once the chemical reaction concluded and nitrogen dioxide gas stopped releasing from the beaker, 20 milliliters of distilled water was added to the solution, and the color within the beaker turned to a neon blue. This was the chemical equation for the first chemical reaction, 4 HNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + H2O (l) + 2 NO2 (g).
Finding and hiring an electrician to do or fix the electrical wiring in your home is not as simple as flipping through the phone book. Many times, homeowners rush into hiring an electrician without doing any background check. They want to get started as soon as possible, and in the process they end up wasting money on an electrician who do shoddy work or charge way too much. If you want an electrician who is good and dependable, not to mention charge a competitive price, you will need to spend some time doing your research. So how exactly do you pick the right electrician? Below are some things you can keep in mind when you are looking for a good electrician.
Video learning is a learning modality that is highly used in many curriculums and different programs. It can be difficult to find videos that are associated with the class lecture, but it can also provide an opportunity to learn off of errors based on self-recordings. In a study by Giles et al. (2014) , occupational therapy students participated in a lab simulation and were video recorded during the entire process.

In the past few decades, one field of engineering in particular has stood out in terms of development and commercialisation; and that is electronics and computation. In 1965, when Moore’s Law was first established (Gordon E. Moore, 1965: "Cramming more components onto integrated circuits"), it was stated that the number of transistors (an electronic component according to which the processing and memory capabilities of a microchip is measured) would double every 2 years. This prediction held true even when man ushered in the new millennium. We have gone from computers that could perform one calculation in one second to a super-computer (the one at Oak Ridge National Lab) that can perform 1 quadrillion (1015) mathematical calculations per second. Thus, it is only obvious that this field would also have s...
Electrolysis Investigation Planning In this investigation, I will assess how changing the electric current in the electrolysis of acidified water affects the rate at which hydrogen gas is produced. The solution to be electrolysed is made up using acid and water. It is of little consequence what acid is used however in this case I will use Sulphuric acid (H2SO4). When H2SO4 is put in water it is dissociated and forms ions: H2SO4 → 2H (2+) + SO4 (2-) Ions are also present from the water in the solution: H2O → H (+) + OH (-) During the electrolysis process, the positive hydrogen ions move towards the cathode and the negative hydroxide and sulphate ions move towards the anode.
As a graduate student, I will undertake research and coursework in Electrical Engineering to enhance my competencies in this field. I intend to complete my master's degree in order to pursue my doctorate. The research that I am most interested in pursuing at Northeastern University surrounds the optical properties of MEMS devices, and the development of substrate-based fast electro-optical interfaces. My interest in this area stems from my undergraduate study in MEMs development for tri-axial accelerometers.
Electrical Engineers research, develop, design, and test electronic components, products, and systems for commercial, industrial, medical, military, and scientific applications (Cosgrove 749). They are concerned with devices that use small amounts of electricity that make up electronic components such as integrated circuits and microprocessors. By applying principles and techniques of electronic engineering they design, develop, and manufacture products such as computers, telephones, radios, and stereo systems (EGOE, 121). Electrical engineers touch everyone lives through the things they have designed or created. Electrical engineers have invented the lights in your house, the television, the stereo, the telephone, computers, and even your doctor’s blood pressure gauge (Stine 300).
My fascination towards Electronics N Communication basically developed in the 12th when I took part in a science exhibition. I was then fascinated with the complexities of different structures and their working. The i...
Electroplating Experiment Aim To find the amount copper gains or loses on the electrodes using different amounts of current each time during electrolysis. How the changing of current affects the electroplating of copper. Introduction Electroplating is generally carried out in order to improve the appearance or corrosion resistance of the surface of a metal by electrodepositing a thin layer of metal ion on it. The metal substrate to be coated is made by the cathode in an electrolytic cell. The cell used in electroplating contains an electrolyte which is usually an aqueous solution containing a reasonably high concentration of an ion of the metal which is to be electroplated on the surface.
A computer is a device which is used for several applications; business, gaming, or school. It’s important for people to know how computers work because in this day and age, operating a computer is an everyday task. This complex electrical device utilizes several parts inside of it to keep itself cool, conduct the proper tasks, and maintain stability. These devices can be found several places whether it be on the job, in one’s room, or on a school campus. Computers are essential for everyday use in order to complete what is required. What each component is and its function will be described.
