War of Currents

Serbian-born immigrant, holds over 40 U.S. patents for advancements in alternating current technology, the type of electricity most used today. The U.S. patent office and U.S. Supreme Court also credit him for advancements in radio. Tesla also invented vacuum tubes that paved the way for television and held experiments that helped engineers create the cell phone. Modern electricity makes use of polyphase alternating current (AC).…

Jersey. It was there that the feud between Edison and Tesla began. That disagreement turned into a full out war Tesla pointed out the inefficiency of Edison’s electrical powerhouses that were up and down the atlantic current. In February 1882 Tesla discovered a rotating magnetic field which is the fundamental principle in physics and the basis of all devices that use an alternating current. As early as 1892, Nikola Tesla created a design for a radio. On November 8, 1898 he patented the radio…

joined the debate in which greatness still eludes a precise definition. Encyclopaedia Britannica lists Nikola Tesla as one of the ‘top ten most fascinating people in history’, a genius in his field of work; credited as the inventor of the Alternating current, the radio…

These are things you probably use everyday. The inventor of the AC motor and radio was Nikola Tesla. One of his inventions, the Tesla Coil, was used in early radio antennas. He was a brilliant man with a powerful imagination. He won the ‘war of currents’ and made lighting. And this is his story. He was born in July of 1856, in the small town of Gospic. He was named after his father, Nikola Tesla. The last name of the Tesla’s is taken from an ax that has a “broad cutting blade at…

death ray could be created that would completely annihilate targets. The idea is that electromagnetic particles would rapidly accelerate in a cannon to the point it could slice a person’s body in half, similar to a knife. His idea was used in Star Wars, as the lightsabers used by all of the jedis. Tesla also believed in sending signals to Mars. Although his ideas back then seemed impossible, today they appear to be…

Specific Purpose: To show the audience that the Thomas Edison we learned in school was actually a lie. Introduction: Attention: Thomas Edison was a great inventor, but did you know he did not have a formal education? According to an article written by US National Parks Service entitled Edison Biography on March 14th, states that Edison was home schooled and his mother taught him how to read (National Parks Service). Even without higher education he became one of the most successful people in…

In the past year, the company GAP has seen a steady decrease in their stock prices which has been caused by a couple of different things. A change in management and poor communication within new management has caused sales to steadily decrease. One effect of this poor communication in management is that GAP’s inventory is not well organized, which hurts the net cash flow of the company. The old system used to order inventory was “by gauging the response [to the product], the management [was]…

thought of the possibility that magnetism and electricity were related. He considered such a possibility because of the observations he made during an experiment. He Placed a wire above a compass and passed a current through the wire. He noticed that the needle of compass moved when current was passing through the wire. André Ampère was greatly inspired by Oersted’s findings and worked on it to create a mathematical formula that later became Maxwell’s fourth equation of electromagnetism in the…

SIMULATION RESULTS AND DISCUSSION 4.5.1 Compensation of Voltage Sags All the proposed controllers performed to the IEEE standard. Table 4.5 shows voltage sag compensation of the proposed intelligent controllers. Compensated SS value shows the voltage sag compensation capability of the each proposed controller under different fault types and load conditions. In case 1, performance of DVR with proposed fuzzy logic controller has the sag score 0.5056pu observed at sensitive load before…

Electrical Properties AC Conductivity, Ac Resistivity, Dielectric loss, and Dielectric constant are electrical properties and measured as a function of frequency. AC Conductivity and Resistivity AC resistance (ρac) was recorded by LCR meter model 4275 in the frequency range 1MHz to 3GHz. AC conductivity was determined by using the value of Ac resistance. As we know, Ac Conductivity is reciprocal of Ac resistance can be calculated by the relation; ac =1/ρac (6) The variation of AC…
