  • Space Charge And Electric Field Distribution

    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…

  • Revolution Steam Engine

    Humanity is a collective group of thinkers, scattered across time and space, and, as such, no invention can be attributed to a single person, rather several people who continue to make innovations and improvements upon the design. It may then be argued that inventions aren't created, but grown through the ages until it is perfected. Such is the case with Thomas Newcomen, who, through improvements upon the design made by Thomas Savery, led to one of the major catalysts of the Industrial…

  • Personal Narrative: My Interview With An Electrical Engineer

    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…

  • Case Study Of Split Die

    3.3.3 Selection of Die Angles The split die was designed for the ease of assembly for fabrication. AISI 52100 steel was selected as the material for the die fabrication. The entry part of the die is 12 mm and has 120 mm length. The profile of the die is also shown in the solid works software. The angle of the die is 90 is maintained, the slope radius is 20 mm. the Figure.3.1 & Figure. 3.2. illustrate the split die design and solid works model of the split die. Figure. 3.1 : Split die…

  • Difference Between Terminology And Unit

    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…

  • Wheatstone Bridge Analysis

    Wheatstone bridge is a device used to measure unknown resistance by passing current through the resistor [1]. Wheatstone bridge is made up of a power source and galvanometer that joins the two-parallel circuits which contains two resistors each. It is very useful in finding small resistances and is used in various applications such as strain gages. The following figure shows the arrangement of a Wheatstone bridge. Figure 1: Arrangement of a Wheatstone Bridge [1] Importance of Wheatstone…

  • The Importance Of Sensors

    A sensor is a device that receives a stimulus, meaurand, or any input signal such as from heat, pressure, light, motion and many more, and responds with an electrical signal. This electrical signal then will decide what will be the result of an output. Depending on the input of the stimulus, the sensor will react to it in a particular way. Sensors are attached to an electrical device and they scan the surrounding environment. Then it converts the input signals to a voltage, current or charge.…

  • Strengths And Weaknesses Of Smartphones

    Technology has significantly advanced for the past few decades, with abundance of inventions created by brilliant minds have filled the current world. One such brilliant inventor that made his name known in the inventing world back in the 1870s was Scottish-born American inventor Alexander Graham Bell, the founding father of the device that could transmit speech electrically; the telephone (Gray, 2011). The telephone was notably fashioned from his attempts to improve an invention that was…

  • Thomas Edison Research Paper

    Thomas Edison a famous American inventor, who invented many life influential devices and one of the first inventors who used mass production stated the following quote. “To invent something takes 1% inspiration, and 99% perspiration.” I agree that to make a goal or an idea reality it takes a lot of hard work. Thomas Edison invented many life changing devices e.g. electric light, sound recording, and motion pictures. My reasons why I agree to the quote Thomas Edison stated is the following.…
