in the market than the copper cables. These cables are widely used in offices or residential areas. Copper cables transmit information through electrical signals. It has been used as a speaker system wire‚ telephone wire‚ computer cable wire etc. for over years now. Optical fiber comprises of plastic or glass strands to transmit data or information digitally with the use of light rather than electricity. On the other hand‚ copper cable encompasses of a single thread of copper. The size of the cable

PHET 8 Battery-Resistor Circuit Name Course Date Learning Goals To visualize the interplay between the voltage‚ resistance‚ current and temperature in a conductor Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move due to voltage of the battery

3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing

Copper is one of the few metals that have been mined for more than 100 decades globally. According to M.G.C Wilson (1989) copper has been mined since the early 3000 BC in Cyprus. In the ancient times copper was used for making tools‚ weapons‚ ornaments and many household utensils. Copper is the third most widely used metal after aluminium (Al) and iron (Fe) because of its high durability (Doebrich et.al‚2009). In the Southern African region copper has been extracted by the early inhabitants long
