A COMPARISON OF ALUMINUM VS. COPPER AS USED IN ELECTRICAL EQUIPMENT Larry Pryor‚ P.E. – Sr. Specification Engineer‚ GE Consumer & Industrial Rick Schlobohm‚ P.E. – Sr. Specification Engineer‚ GE Consumer & Industrial Bill Brownell‚ P.E – Specification Engineer‚ GE Consumer & Industrial ABSTRACT The debate over the pros and cons of aluminum vs. copper conductors has been discussed for many years. Many of the concerns are based on old information and also misinformation. These concerns center on the

Copper Sun By: Sharon Draper The novel Copper Sun is a searing work of historical fiction and is action-packed‚ multifaceted‚ and character-rich. It describes a young girl’s life that was stolen from her village‚ sold to the highest bidder‚ enslaved‚ beaten‚ and mistreated. It expresses the different emotions that were felt as the girl went through her long and tiresome journey. Throughout‚ the young girl named Amaris journey‚ she encountered several different characters with similar but different

: The copper cycle IN TRODUCTION The purpose of the experiment is to recognize that change of state‚ change in colour‚ formation of a precipitate‚ or the evolution of heat are associated with a chemical change; to study reactions of copper. Copper is an element that can be found in nature in a variety of different compounds. The most common natural ore is the sulphide‚ known as chalcocite‚ Cu2S. This mineral is an important source of copper metal because it is about 80% copper by weight

Daniel Osherow ENGR 1301 5 December 2012 Copper Wire Sizes (EE) The diameter of a copper wire is measured by using a system called the American Wire Gauge also known as AWG. This system has predominantly been used in the United States and Canada since 1857. Using this measurement the cross-sectional area of a gauge is able to be found. We then use this area to determine the wires current carrying capacity. The gauge numbers for wire and diameter values work inversely‚ as when one increases the

Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

Graphene replaced with copper Graphene nanoribbons have a current-carrying capacity two orders of magnitude higher than copper Recent research into the properties of graphene nanoribbons provides two new reasons for using the material for interconnects in future computer chips. In widths as narrow as 16 nm‚ graphene has a current-carrying capacity approximately a thousand times greater than copper while providing improved thermal conductivity. The current-carrying and heat-transfer measurements

resistivity of different sized copper wires? Hypothesis I think that the resistivity will increase with higher temperatures because with higher temperature‚ resistivity is higher due to the fact the atomic lattice structure increases. Background Electrical resistivity is the measurement of how a material opposes the flow of an electrical current. On the other hand‚ electrical conductivity () is the inverse of resistivity. It is the measurement of how a material accommodates to electrical

Copper was the first metal that is used by humans as weapons and tools. It is shinny and has a reddish brown color. It’s application toward humans has really changed the way we live. Copper is an excellent conductor of electricity‚ which is often used as electrical wires or cables in generators‚ motors and electric products. In addition‚ it is also an outstanding conductor of heat‚ which is used in radiators and heating systems. Since it does not react with water and corrode easily‚ it is widely
