What was the horsepower calculated? Does this make sense? The horsepower calculated when running up the stairs was 0.67 hp. This makes sense as 1 hp was originally defined to be the approximate amount of work a strong dray horse could do while lifting coal for one minute (The Editors of Encyclopædia Britannica, n.d). It is, therefore, reasonable to assume that a human could do 67% of this amount of work for a shorter amount of time. Generator What would happen to the force required to turn…

Ervin Akoopi Nikola Tesla was a Serbian American. His grandfather, Duka Tesla had much talent for creativity. Nikola admired Duka's memory which was passed down through genetics from his mother. Tesla was intelligent. He performed integral calculus in his head, in which his teachers thought he was a cheater. He finished a 4 year term through 3 years at a university. At this time, Tesla’s father, Mulitin, knew his son was a scholar. Tesla was asked to make a catalogue for the library for the…

In this report I will explain how a motor works. Fig. 1 shows the parts of the motor. In this motor, there are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets,…

Thomas edison was a famous inventor from Ohio. His inventions brought light to the people. He also brought music to people's lives. I will be telling facts, inventions, and the life of Thomas Edison and it is all it this project. Who is Thomas Edison? Thomas Edison was an inventor and he was born in 1847. He died in 1931. He lived with his sister Nancy and his brother Samuel. His family includes his sons, Charles, Theodore, William, sisters and brothers William, Samuel, Marion, Eliza, Carle,…

Few home owners really take the time to understand their home's electrical system and how electricians ensure that it is safe. However, by understanding this process and how it applies to your home, you can avoid unsafe wiring and non-compliance situations that can expensive to fix and dangerous to your home. Understanding The National Electrical Code The federal government has created a guideline for electrical wiring safety that is known as the "National Electrical Code." It has been adopted…

The world has been influenced by many of people throughout history. One person in particular has done such a thing that we use it on a daily bases, and not even notice. Nikola Tesla was an inventor that developed the AC electrical system. This system has changed the world of electric once it was developed but it wasn’t till a partnership that went bad till it came about. Tesla may have invented this but did he get the recognition that he deserved, well that’s what we are going to find out.…

Electrical Engineering at Qualcomm: Profile Essay Final Draft You all might have heard of the company name “Qualcomm” at least one time in your life, whether you think about the research centers that designs and promotes wireless telephones and services or the one that’s most common, which is Qualcomm Stadium, where all home games are played at for the NFL’s football team, the San Diego Chargers, as well as for San Diego State University Aztecs college football team. I will be referring to the…

This chapter contain the physical model and numerical procedure of calculating the dynamics of space charge and electric field distribution in cable insulation material under DC voltage. Electric field distribution and formation of space charge The dependency of electric field distribution on time and temperature is obvious in HVDC system. This is due to the resistivity/conductivity dependency on temperature and electric field [1, 44]. It is also clear that the formation of space charge within…

Terminology and units Current Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is the uppercase letter I. Potential difference The potential difference between two points.The units for potential difference are Joules per coulomb, or volts. (1 volt = 1 Joule/coulomb). Electrical charge Electric charge is carried by the electrons ( negative charge) and protons (positive charge) within an atom. The…

When I was first asked to do this interview assignment, I was very concerned as to who I would be interviewing. I did not want to interview any random Engineer because it would not be pertinent to my future career. The few people I would be able to interview that were family friends, were not Electrical Engineers. I knew of a Civil, Chemical, and Mechanical Engineer, none of which I found to fit my assignment. I wanted to specifically interview an Electrical Engineer because they would be able…
