Alternating current

Problem: The research questions being examined in this investigation is, How can we generate electricity by using Potatoes to light an electric bulb? Background Information: How does a potato battery work? The copper (Cu) particles pull in electrons more than the zinc (Zn) molecules. On the off chance that you put a portion of copper and a piece of zinc in contact with each other, numerous electrons go from the zinc to the copper. As they focus on the copper, the electrons repulse each other.…

*** Luigi Galvani used an electrostatic machine that produced sparks on frog legs and began to investigate the muscular contractions produced by electricity. Galvani discovered that the frog leg would contract if a scalpel touched the frog’s nerves when the machine was on.
 More comprehensive experiments by Galvani showed that a dead frog’s leg could be made to twitch by electrical stimulation. Galvani also showed that the same twitching could be produced by touching the leg with a copper hook…

This is resistance, which is measured in units called ohms. Resistance is a term that describes the forces that oppose the flow of electron current in a conductor. All materials naturally contain some resistance to the flow of electron current. We have not found a way to make conductors that do not have some resistance. If we use our water analogy to help picture resistance, think of a hose that is partially plugged with sand. The sand will…

Growth of Mittal Steel Edwin Romero Ashford University BUS616 International Business Dr. Johnny Vanneste November 10, 2014 Abstract In today’s world for a company to be able to grow and compete on a level higher than its competitor’s it must eventually seek to move outward into new markets. This growth will not only assist the company in its need for expansion but it can also be beneficial to the local communities the organization moves into by providing jobs and other economical…

Financial Overview Cara Operations is a pretty large company, with total dollar sales of $900.5 million (Cara Reports Q2 2016 Results, 2016). Market capitalization is equal to the current share price of the company multiplied by the number of outstanding shares of the company. Cara’s current stock price is $24.84 and their number of shares outstanding are 24.43M. Therefore, Cara’s market capitalization would be $24.84 x 24.43M = $606.8M. CHL will continue to hold 14,492,906 Multiple Voting…

With so many issues going on in the community, it may be a good idea for the community to use its resources to its own advantage. The idea is to improve conditions to make our community a better place and solar energy is one way of solving multiple problems with one solution. By using solar power, it eliminates chances of being harmed by loose or dangerous power lines, therefore improving safety hazards. Society has come a long way thanks to pioneers such as Benjamin Franklin and Thomas Edison,…

is pursuing market penetration strategy and related constrained. Tesla intends to enhance their influence on the current markets with their current products. They also market their electric powertrain components to other automakers (2014).” Tesla is really focusing on working on market penetration and all related to it, so the company wants to penetrate in the market using their current products and offering tis product to other car companies. However, it is important note that the company not…

The magnetohydrodynamic phenomena are a consequence of the mutual interaction of the fluid flow and the magnetic field. As is well known, a conductor crossing magnetic field lines gives rise to an induced electric field, which causes an electric current in the conducting fluid. The following are the Maxwell,s equations ∇⋅D = ρcf ∇⋅B = 0 ∇×E = −∂B ∂t ∇×H = J f + ∂D ∂t…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…

create a model that transmits electrical current and demonstrate that electricity travels in a closed path. Materials: (6) light bulb, (6) battery, (6) 6 in. insolated copper wires, (6) wire stripper, (6) switches, (21) safety goggles, (21) aprons, and boxes of gloves. Vocabulary: Circuit, closed circuit, open circuit, electrical circuit, electromagnetic, and parallel circuit Engaged: We are going to do a KWL chart to find out, what you know about electrical current, what you want to know, and…
