Circuit Lab Report Sample

Circuit Lab Report Paper A millimeter is an instrument designed to measure electric current, voltage, and usually resistance, typically over several ranges of value. The millimeter has different programs to measure voltage, current, resistance, etc. Produced from one of two types of circuits. The first type of circuit is a series circuit. A series circuit is a circuit in which the components are arranged end to end in such a way that the electric current flows through the first component, through the next component, and so on, until it reaches the source again. In contrast, a parallel circuit is a circuit in which the has more than one resistor and as multiple paths to move along. The main purpose of this lab was to prove the laws of Ohm and Kerchief. On another note, being able to take part in this lab taught my partner and I the fundamental skills of constructing series and parallel circuit and using a millimeter to calculate the current and voltage of a circuit. Live that if we only have the basic materials to conduct electricity (such as resistors, alligator clip, cords, a millimeter, and a power source), then we can still prove the that the laws that Ohm and Kerchief established are in fact reliable resources for calculating data regarding certain electrical circuits. Vive reached this hypothesis because Ohms laws and Kerchiefs two laws are supposed to be laws used for any electrical circuits. Based on this, these three laws should be able to be validated With this experiment.

Assemble circuit as seen in figure 3 and set millimeter back to current 2. Install at all three points at both junctions 3. See if the current entering the junction is equal to the current leaving the junctions Discussion Our lab in general, went fairly well. We took our time and did not rush through his lab, sows could get the best results, but we did have some trouble with our Millimeter on more than one occasion, For example, while we were attempting to price Ohms Law and Kerchiefs Voltage Law. The Millimeter, at first was acting up and completely just not working, but we then realized that it was not set on the correct measuring task. Then, on the same two labs, we were getting readings from the Millimeter that made no sense, It told us that the current for the circuit was 367. 83 Ohms which for the type of circuit that we built, was impossible. After fixing the problem with the Millimeter and proving Ohms Law and Kerchiefs Voltage Law, eve moved onto the Current Law that Kerchief established. This time, the problem wasnt the Millimeter, or the resistors, or the power supply, or anything else. It avgas us. We were overall a bit confused on how the circuit was created and it took a long time to eventually construct and then prove. Even though the problems were an annoyance, the lab was very insightful and taught us a lot about electric currents and circuits. Conclusion At the conclusion of this experiment, our results supported our hypothesis greatly even though our numbers were not a hundred percent on point. But here is room for error, like the fact that the power supply was not great quality and doesnt give exactly 3 volts or 4. Volts or any of that, Also, the resistors are not high-quality resistors and are also worn down trot years of use, so they dont give exactly 11000 / 10,000 Ohms like we were looking for. Other sources tot error included the Millimeter, which was not exact because the Millimeter rounds numbers, the Alligator clips, which are (like the power supply and resistors) not the best and shed energy, and our calculations, which could have suffered from any addition or multiplication or division error,

Discuss the Relationship between money and Ideals in Howard essays

Discuss the Relationship between money and Ideals in Howard essays The attempt to connect the two different worlds of money and ideals is a central theme in E.M Forsters Howards End. The concept of money is most strongly represented by the Wilcox family. Idealism and intellectualism are the driving forces of the Schlegels especially the younger sister Helen. Establishing the rainbow bridge (page 187) between these two is Margaret Schlegel, the novels protagonist. The central relationship in the novel is between Henry Wilcox, who has made his fortune through the rubber industry, and the elder Schlegel sister, Margaret. The novel follows their courtship and consequent marriage through a journey of obstacles and revelations. Henry Wilcox is driven by money and power with little time for culture and intellectual thought. He is obtuse but also kindly. Margaret is an intellectual who cares for the troubles of the world but cares most for the welfare of her siblings and her husband. The other characters in the novel represent more extreme types. Helen, Margarets much loved younger sister, is a bohemian idealist who responds passionately to situations. Charles Wilcox is the most prosaic character. The clerk, Leonard Bast, is tormented by a glimpse of societys privileged he is at the extreme verge of gentility and though not in the abyss (page 58) he is aware of it. His gaudy wife, Jacky, represents the seedier side of society. She is in the abyss but does not seem aware of it. Mrs Munt (Aunt Juley) is awfully English, with little genuine understanding of Art and Literature but a great understanding of its importance in cultured society. Mrs Wilcox represents an ideal wife, a gentle diplomat who is not passionate about anything that might be controversial but is passionate that people should have a home. The upbringing of the Schlegel sisters is one of liberal idealism from their German fa...

Types of composite materials Research Paper Example | Topics and Well Written Essays - 1500 words

Types of composite materials - Research Paper Example One good example of a composite material is the disk brake pad. The disk brake pad is made up of ceramic particles that are often times entrenched in soft metal matrix. Other examples include shower stalls, bathtubs and fiberglass. A mud brick is made up of clay, mud, sand and water in a process that is free of fire and is mixed with the aid of binding material including rice husks, coffee husks or maize chaff. This has been practiced since time memorial in the ancient civilization. In mud bricks the matrix is the mad whereas the reinforcing materials are the rice husks, coffee husks or maize chaff. Mud bricks are known to perform well under compression, however when bending forces are exerted on they tend to cave in. This, on further explanation is due to bending forces exerting a tension force. Mud bricks tend to resist pulling forces acting on them, but they tend to be weak when they are crumpled. It is common practice to leave the stiff mixture to dry in the sun for duration of about four weeks. This is common in places where the weather is warmer and there is diminutive timber to provide for the fuel for use in kilns. The use of stucco has been used to increase the life of mud bricks when the kiln dried mud bricks are placed on them. Mud bricks are used in construction industry for building houses, for example, in the implementation of adobe which is an energy saving and environmentally safe way to insulate a house (Measures 126). It is also used in constructing insulation material such as furnace. In this case it could be used to melt metal such as aluminum for making aircraft components. Laminate is a kind of composite material that is made up of layers or lamina that have unidirectional composite material. Some of the examples of laminar composite materials include continuous and aligned fiber reinforced plastics with matrix such as epoxy and polyester (Inova 56). In the
