Alternating current

I. Purpose: The purpose of this lab is best understood by the principles of static electricity, as two rough objects rub against each other the atoms of those objects touch and pull upon each other sporadically. When this occurs the electrons of those atoms will transfer between these objects and static electricity is generated. This lab is performed to see the role that static electricity has on objects, when determining their charge and how they interact, all seen by a firsthand course of…

The science experiment that my partner and I are going to test is, do different brands of batteries affect the electric current of an electromagnet? Electromagnets are magnets that can be powered on and off, they can do simple tasks such as ring doorbells to surgically pull a steel splinter from your eye (Stringer). There are many factors that may affect the way electricity flows throughout metals. For example, the number of coils wrapped around the metal object may affect its magnetic strength.…

In the two articles and the video I read and watched, they all had some sort of description of electricity. I think that the purpose of each is to get the reader or viewer to learn something about electricity. In Energy Story the main idea was to teach and tell the reader about how we use appliances or things that use electricity almost every day and sometimes without even knowing. Energy Story also teaches you about atoms and how they are made up of protons, neutrons and electrons. The passage…

Introduction The purpose of this report is to critically analyze Lincoln Electric Company as a whole. We will extract strategic issues that this business faces and offer our professional opinion on how to best tackle these problems. In this analysis we will be focusing on the company’s financials. After assessing their financial situation, we will address their employees’ satisfaction as well as their compensation. Finally, the management style and Lincoln’s production and manufacturing process…

Factors That Contribute to the Digital Divide Transportation One of the crucial factors that contribute to the difficulty to spread technology and business to much of India is the lack of easy transportation. Of the over 1.34 billion people who populate India, 72.2 percent live in 638,000 villages while the remaining 27.8 percent live in only 5,480 towns and urban agglomerations (Population of India 2016, 2016). While urban cities have some paved roads and public transportation means such as…

control complexity in application. where no isolation and high output current with low ripple. An No isolation DC/DC converter Fig.1.1 shows the step-down DC/DC converter. When switch M is on for the duration of dTs, power is transferred from source to load and filter inductor L is charged. When switch M is off for a duration (1-d)Ts, the diode D becomes forward-biased and forms a conduction path for the filter inductor current. The voltage across the filter inductor is the reverse of the output…

The Anode What is Anode? What is anode fabricated from in Li-ion battery? What material could be replacement of ion material however failed? What is design and structure of anode in Lithium ion(Lithium ) battery? What is the reaction/process that are undergoing in anode? What are the recent advancements in anode of Lithium ion(Lithium ) battery? What are the challenges that are still left in the field? 1) The anode is the negative electrode of a galvanic cell and is related to the oxidation…

semiconductor behaves as Insulator 3. Define electrical conductivity. Electrical conductivity is the ability to conduct an electric current. 4. What are the two types of charge carriers in semiconductors? Electrons and holes are the two types of charge carriers in semiconductor. 5. Define charge carrier. Charge carrier is a particle, which carries electric charge or electric current from one place to another place. 6. Define hole. The absence of electron in the atomic shell is called a hole. 7.…

free electrons. Copper has one free electron per atom. The free electron concentration in copper is 8.5 x 1028 per m3. The electrons start flowing as soon as the switch is closed. But the electrons themselves travel much more slowly. So how does the current come on everywhere as soon as the switch is closed? It is because the free electrons are already spread throughout the wire. As soon as the switch is closed, there is a force on all electrons (i.e. electric potential difference) which causes…

Galvanism is animating a dead corps by electrocution throughout the body. Luigi Galvani was not the first person to think of pulsing electricity through the body, but he was the person who determined that electricity was present within the body itself. The electricity animates the dead body and causes it to move through muscle movement. Luigi Galvani founded this idea in 1791. Genetic engineering is a variety of techniques that cut up and combine different genetic material to create or change a…
