    Tesla and Thomas Edison started to skyrocket after Tesla quit his job with Edison when he didn’t accept the improvements Tesla proposed for his DC system and the War of the Currents began, with Tesla on team alternating current (AC) and Edison on team direct current (DC) (Uth). During this, in 1888, Tesla’s alternating current system caught the eye of George Westinghouse and he was offered $60,000 in cash for his patents and $2.50 per horsepower generated by a Tesla device, eventually leading to the

    What is Current. 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

    Tesla and Thomas also had more inventions than Tesla, also because Edison did a lot of work with the light bulb. Although they both had a big part in controlling electricity one was for Alternating Current electricity and one for Direct Current. Nikola Tesla was against Direct Current and left with Alternating Current and Edison was for DC and so Nikola and Thomas were up against eatchother to see which one was a much better use.

    The Earth is not a piece of quartz - it’s like a stone with many imperfections and scratches, and though it retains its scratches, it attempts to heal them; it bandages its wounds. To heal a wound, though, it must be first isolated: and in the case of the world, it is literal flaw that resides with the mask of a wound - combated, though not incapacitated, by the innovators of the Earth. A telephone, refrigerator, microwave, civil rights and gender equality - not only technology, but even a concept

    people do not understand is the fact that if the “Wizard” had his way, there would be a power plant every several miles, scattered about the land like sprinkles on a cupcake. At the time, direct current was the only choice, inhibiting as it was. Then, thanks to a man names Nikola Tesla, an alternating current motor was invented, allowing much more efficient electricity travel. This is just one example of the impact Telsa has had on the modern world. The forgotten father of science, Tesla, is responsible

    to bring his plan to life. He succeeded many times with electrical generating equipment like the numerous variations of the Tesla coil. Alternating current is probably the most important invention of his collection. Without it, there would be no wall outlets for the easy plug-in of everyday devices. The world's population would still be using Edison's direct current method of electricity. Nikola Tesla may have seemed like someone who was not that important to the lifestyle of the modern era, but without

    module i learned about two types of electrical current, alternating (AC), and direct current (DC). In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in (AC) circuits also periodically reverses because the current changes direction. Electrical lineman work on power lines and other thing that have (AC) or (DC) current depending on what they are working on. Lineman

    Company. While at Graz Technical University, Tesla had seen a demonstration of a generator run as a direct-current (DC) motor. Direct current is electric current that flows in only one direction. During the demonstration, the brushes and the commutator of the motor sparked violently. The brushes are devices that conduct the current in a DC motor. The commutator continually reverses the current so that the motor continues to rotate in one direction. Tesla believed a motor without a commutator could

    Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must

    stop working afterwards. I lost interest in those batteries once I discovered the power of alternating current. In fact my favorite toy growing up was an old electrical power cord that had been pulled out of a lamp. I don’t remember where I found it. Maybe in one of those boxes on the shelves, or more likely, I cut it off a lamp myself. I used to run tests where I’d send 120 volts of alternating current through various materials, and observe the results. My favorite objects to observe were metal

    converted to light, start with a standard U.S. 60-HZ AC (alternating current) wall circuit with a nominal root mean square (rms) voltage of 220. An alternating current is created by, electrons moving in one direction and then reversing to move in the opposite direction. Because of this process in electron motion the AC is constantly establishing, collapsing, reestablishing, and re-collapsing its surrounding magnetic field. The incoming line current will supply power in the form of a three-phase power
