• ## Finding The Magnetic Fields Of The 3 Wires

a) According to the right-hand rule, the direction of the magnetic fields of the 3 wires are shown: We find the magnetic fields B1, B2 and B3: 퐵1=퐵2= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟒퟐ.ퟔퟔퟎ풖푻 2휋푟 2휋( 2푎) 2 ∗ 3.14 ∗( 2(0.0121)) 퐵3= 푢0 푖 = 푢0 푖 = 4∗3.14×10−7 ∗(3.65) =ퟐퟎ.ퟏퟏퟎ풖푻 2휋푟 2휋(3푎) 2 ∗ 3.14 ∗(3∗(0.0121)) The x components of the B1 and B2 cancel each other; therefore the net magnetic field will be downward and we have (the negative sign is because the direction is downward): 퐵=− 퐵1cos 45 +…

• ## Essay On Nikola Tesla

Nikola Tesla The inventor Nikola Tesla lived from July 10, 1856 to January 7, 1943, he was a well-known engineer who designed the alternating-current (AC) electric system. He was born in what is now Croatia; he came to the United States in 1884 and worked for Thomas Edison for a while before they both went their separate ways. Tesla sold several patent rights to George Westinghouse; one of those was his AC machinery. During Tesla’s career he discovered, designed and developed ideas for a number…

• ## Tesla Coil Essay

In essence, Tesla coils are a high-voltage, resonant transformer circuits. They consist of the six major components (Behrend 1), namely: Primary transformer Tank capacitor Spark gap Primary coil Secondary coil Toroid Figure 1: Tesla coil (diagram) A primary transformer is a step-up transformer that takes the line voltage of the AC source and steps it up to a range between 12 kV and 50 kV at 60 Hz (Johnson 4). The efficiency of this transformer is largely dependable on the construction…

• ## Case Study: Direct Current (DC) Motors

Direct Current (DC) motors Name: University 1.0 Introduction A Direct Current (DC) motor is one of the broader classification of electric motors which operate from a direct current. Nearly all mechanical devices applied in daily life activities are powered by electric motors. Motors transform electrical energy to mechanical energy, hence they are essential for energy conversions in electrical machines. All types of electrical motors are made up of a stationary field referred to a stator and…

• ## Analyse The Value Of Voltages In Generation, Transmission And Distribution?

generating station 's electrical power distribution system, which provided 110 volts direct current (DC) to 59 customers in lower Manhattan. However Edison became stuck, as in order for his system to work he would need to have power stations scattered every mile to make it economical. Which wouldn’t work, the reason being that to bury the cables would be very expensive and the cables would also lose current over long distances, because of the resistance inside…

• ## Climate Change Affect How We Will Live In The Present And Future

Everything that we do on this planet can affect how we will live in the present and future. Throughout the years of developing a better world, we have also destroyed it in the process. As we continue to do our ways of inducing climate change, the outcome of a larger and a lot more dangerous disasters is inevitable. The world we may live in may change for the worst. Climate change is a way of understanding how molecules can affect other molecules differently in an environment. This change can…

• ## Death Penalty Reforms

Moving into the nineteenth century, the abolitionist movement surrounding the death penalty began to come into effect. Many reforms were seen in many states during the early 1800s, including giving the jury discretion in imposing the death penalty and limiting the types of crimes (down to two in New Hampshire and Ohio by 1815) that were eligible for the death penalty. This is time when juries began to utilize their own power through the controversial actions known as “jury nullification,” in…

• ## AC Conductivity, Dieedric Loss, And Dielectric Constant

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…

• ## GAP Case Study Essay

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.
