RE: Electrical Lab Report
The purpose of this project was to apply the engineering design process to a simple electrical circuit problem. The goal is to design and build a specific electrical circuit. A small breadboard, 25 common resistors, and jumper wires were given to construct a voltage divider. The project requires students to understand Ohm’s Law, Kirchhoff’s Current and Voltage Laws.
The project can be broken into two parts. The first part is solving voltage drop and resistance needed to drop that much voltage. The second part is to use the resistors that were assigned to reach the resistance as calculated previously. In order to have as much as close to resistance needed, the resistors need to be in series, parallel, and combination.
The individual electrical circuits were tested in class and the result of my design was pretty successful. All the voltage drops between nodes were very close to the ones were specified.

Background information:
1. Electricity:
“Electrons are the negatively charged particles that orbit around the nucleus of an atom and electricity is the flow of electrons. Electricity must have a complete path to travel, or a loop, before the electrons will move.” (Electrical Theory Pre-Class Reading)
2. Ohm’s Law:
Ohm’s Law is the relationship between voltage, current and resistance.
In the article,"Energy Story", it tells you all about basic energy and how scientists found out how it works. It tells you about each part of an electron and what part is what. The center is called the Nucleus. Electrons and atoms move together to create what is known as electricity. Atoms and electrons flow through an object
Atoms have three subatomic particles, protons, neutrons and electrons. The atom, the smallest unit of matter which means it’s the smallest thing that takes space and has mass is so small it would take a million of atoms to cross this dot. Knowing they’re incredibly tiny, the electrons having a single negative charge; they move around the nucleus where the protons with a single positive charge and the neutron who does not have a charge are packed. Electrons are only ones that are involved with the chemical activity of an atom, thus, the more electrons an atom has the more energy it will possess. Electrons aren’t just moving around the nucleus, they move around by levels called electron shells. The first level can hold two electrons, the second and third can hold up to eight electrons.
Metals contain a sea of electrons (which are negatively charged) and which flow throughout the metal. This is what allows electric current to flow so well in all metals. An electrode is a component of an electric circuit that connects the wiring of the circuit to a gas or electrolyte. A compound that conducts in a solution is called an electrolyte. The electrically positive electrode is called the anode and the negative electrode the cathode.
My knowledge of engineering is reasonable and includes transformer substations, power plants, power distribution and transmission systems, industrial motor control and PLC programming, protective relay coordination, FACTS devices, grounding systems, Matlab programming and project management. In addition, I possess practical experience performing power flow, short-circuit and relay coordination analyses while using a power system modelling software such as ETAP, EDSA, DigSilent and CYME. Consequently, the aforementioned experience and solid engineering education along with your training will allow me to provide support to operating and new
For more than 25 years, The Little Black Book of Project Management has been introducing project managers to the incredibly effective and logical project management skill and methods to help them achieve their goal. This book has been flooded with very nee project management techniques as well as the latest standards of the Project management body of Knowledge (PMBOK) .accepted by PMI (Project Management Institute).
traveling this alternate route, the electrons form a current, ergo energy. Once the protons and
To understand how this electricity works we must start with the basics. The atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electric charges that are the same repel each other and charges that are different attract each other. Electric charges can exist alone, unlike magnetic poles.
The implications of this experiment are that the electron does have a charge since its trajectory was altered in the presence of either an electric or magnetic field. It can be shown that in a uniform magnetic field the path of an electron was circular and parabolic in a uniform electric field.
Do you ever wonder about what happens with electricity? In the article “Energy Story” written it tells you about atoms and what things need to have to be that type of object. In the article “Conducting Solutions” by Rodney Schreiner tells you about solutions and the reactions to them with electricity. In the video clip “Hands-on Science with Squishy Circuits” by AnnMarie Thomas it tells you about how simple play dough can hold electricity.
In this paper, I will talk about how AC circuits can be described by considering voltage and current using complex numbers. An AC circuit requires two separate numbers to be able to completely describe it. This is because it takes into account the amplitude and the phase of the current. The fact that complex numbers can be easily added, subtracted, multiplied or divided with each other makes them ideal for this operation where both amplitude and phase have to work together.
First off, what is current. Current is expressed in a unit called Amps. Amps are a measurement of how many electrons pass per second. That is to say, a wire with 40 coulombs passing any point in a 2 seconds would be said to have 20 Amps of current (40 Coulombs (a unit of charge given as 6.24x1018 electrons) / time in seconds or in this case, 2 seconds. The Amp is also known as Coulombs per second) Another trick about current is that it is measured in the movement of the positive charge. Literally that is to say the current moves in oppostion to the electrons. This is because originally it was thought that the positive charge is what moved, both are viable, but in reality a positive charge is generally fixed since within an atom the electrons are migratory, while the protons and neutrons tend to be stationary.
In the process of producing electricity, the anode in a battery produces electrons through an oxidation reaction while the cathode accepts these electrons creating electron flow [4]. Electrons are being carried and transferred by the electrolytes – that acts like a piece of metal between the anode and the cathode [4].
Humans these days take electricity for granted. We don’t truly understand what life was like without it. Most young adults will tell you their life does not depend on electricity, but they aren’t fooling anyone. They all know that their life depends on electricity; whether it’s television, their phone, Google, or the lights in their house. We need to stop taking those things for granted and give credit where credit is due. That is why I chose to write about the scientists who contributed to the discovery of electricity, which then helped modern scientists fuel the electricity phenomenons we now have today.
The chapter ‘Project Management in the Automotive Industry’ by Christophe Midler and Christian Navarre from The Wiley Guide to Managing Projects (September 2004) traces the inception and transformation of project management in the automotive industry from the post-war period to the early years of the new millennium. It is an interesting article which categorizes the period into four phases on the basis of organizational structure and strategy pertinent to most of the automotive manufacturers in each era. This classification helps the authors elaborate on the change in corporate structures and relationships within the organization and with their subcontractors over the years. Examples of leading car manufacturers have shown how project management has developed into an essential aspect of managing complex activities, and how the automotive industry has steadily evolved from being function-oriented and bureaucratic to being innovation-oriented and modular.
Project based learning, also known as PBL, is a teaching method that encourages students to take their education into their own hands. The definition I found for project based learning is, “ A teaching method in which students gain knowledge and skills by working for a n extended period of time to investigate and respond to an engaging and complex question, problem, or challenge” (What is project based learning (pbl)?, n.d.). It helps students communicate with each other and think critically about the world around them. Many schools has already tried to incorporate project based learning into their curriculum. This form of education is students based and the teachers responsibility is to guide the students. While researching, I learned many
