At this moment, Edison’s dream would quickly become a reality as large cities with power stations began adopting Edison’s DC electrical grid. However, it would take the work of Tesla and Westinghouse before the modern AC/DC current would be created. The alternating current could more easily be converted into high voltages, which are easily transported over large distances with fewer losses due to resistance that occurs naturally in any type of wire. This allowed a smaller number of power…

for lenders. Additionally, the company’s current ratio, a ratio that divided current assets by current liabilities to show a businesses ability to meet its current obligations, is currently a strong 5.99 (Appendix 1). Also, the current ratio has increased every month for the past seven months (Oct. 1990-March 1991, excel sheet). The current ratio suggests that Dynashears is currently in good financial standing, and that there ability to meet their current obligations is improving. However, there…

But in Norton’s Theorem the equivalent circuit has a current source and a resistance in parallel with the load resistance (R_X). Continued on next page: HOW IS IT USED When using Norton’s Theorem the load resistance is removed and replaced with a short (wire) and points labeled A and B. The reason to label the points A and B is to show where the meter would measure the unknown voltage and current associated with the load resistance. Next the load resistor is placed into…

material resists current, and is measured in Ohm-meters (Ω-m). Electrical resistance (R) is the opposite of the flow of electrons, or the passage of an electrical current. Electrical conductivity (σ) is the opposite of resistivity and is measured in Siemens (S). Electrical conductivity is defined as; the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field which causes the flow of current. In this…

Principle 1: Money has a time value The hypothesis behind money has a time value is the value of money today is more valuable than the same amount in the future due to its potential earning capacity (Titman, Kewon & Martin, 2014, p. 127). If you have a dollar in your wallet today, that dollar will be worth less in a year’s time if the dollar remains in your wallet. Inflation has an effect on the time value as it increases the price of goods and services over time, decreasing the amount of…

fields. When they truly arrange themselves, they can produce a single magnetic field over all. Some permanent magnets are used in the basis of electromechanical device. The electromagnets are magnets controlled by electricity and the electrical current makes a magnetic field. They use negative and positive poles to make the magnetic fields. Some soft magnetic metals can be strengthened or weaken by how much electret is flowing to electromagnet. The magnets they can use the flow from a…

Robert Fulton was an American engineer and inventor in the 1800s. He is best known for successfully creating the commercial steamboat, “The North River Steamboat of Clermont.” What some do not know, is that he was also a painter, a canal engineer, a philosopher. Although Robert Fulton did not invent the steamboat, his participation in developing new machines for naval warfare was more significant than his involvement with “The North River Steamboat of Clermont.” In fact, some may say that he was…

1.1 Dielectric Materials Dielectric materials are insulating materials that exhibit the property of electrical polarization. Dielectric materials support charge by acquiring a polarisation in an electric field. 1.1.1 Electric susceptibility and permittivity When a capacitor with capacitance C0 is filled with a dielectric material, its charge storage capacity (capacitance) increases to a value of C. Than susceptibility (χ^') of the dielectric materials is given by χ^'= (C-C_0)/C Dielectric…

magnetism and electricity. This paper will give backgrounds on both Faraday and Oersted and will compare and contrast their works. Michael Faraday was born in London on September 22, 1791. He was the first person to produce an electric current from a magnetic field, He discovered diamagnetism and explained why some substances react opposite to a magnetic force when they encounter a magnetic field. He also discovered the effect of magnetism on light and he invented the electric…

Dipole-dipole array has wide using in resistivity/I.P. surveys because of the low E.M. coupling between the current and potential circuits. The arrangement of the electrodes is shown in Figure( )., Electrodes c1 and c2 are separated by a distance (a), and electrodes p1 and p2 are separated by a distance (b). the distance between the potential electrodes pair c1-c2 is the same as the distance between the potential electrodes pair P1-P2 and the distance between the centers of the respective…
