Chemistry assignment help, why nichrome and not copper is used as heating element, explain why nichrome and not copper is used as heating element whereas manganin is used as standard resistance for heating elements, primary requirements are high melting point, high electrical resistance and low. It's a simple question, what's so special about nichrome (nickel chromium alloy) wire that makes it suitable as a heating element the important factors are its high electrical resistivity, its high temperature corrosion resistance and high melting temperature of 1400 degrees c. Electricity (ppt ) different electrical components have different resistance for example, nichrome wires have a higher resistance than copper a kettle uses both copper and nichrome wirescopper has low resistance while nichrome has high resistancewhich. Start studying ch 133 electricity- current, voltage, resistance learn vocabulary, terms, and more with flashcards copper or nichrome copper which materials has high electrical resistance plastic and rubber.
Obviously nichrome because resistivity of nichrome is greater than that of copper as mention above, both wires are of same length and having same cross section areatherefore resistance of nichrome wire will be more than that of copper since mor. Best electrical conductors: silver, copper, gold, aluminum, calcium, beryllium, tungsten the more scattering, the higher the resistance electric resistance electric-current electric-resistance. Nichrome (nicr, nickel-chrome, chrome-nickel, etc) is any of various alloys of nickel, chromium, and often iron (and possibly other elements) the most common usage is as resistance wire, although they are also used in some dental restorations (fillings) and in a few other applications. Papers title: investigating the resistance of nichrome my account investigating the resistance of copper iron constantan nichrome 10cm (1) 03 05 11 23 10cm (2) 04 although all metals are conductors, some have a higher resistance than the other [tags: papers] 1719 words. Answer to problem (a) calculate the resistance per unit length of a 22-gauge nichrome wire of radius 0 question would replacing the nichrome with copper wire of the same size result in a higher current or lower calculate the resistance per unit length of a 44 gauge nichrome wire of.
In this experiment i am going to use copper and nichrome wire i predict that the nichrome wire will have a higher resistance than the copper wire. Resistance versus temperature in a nichrome wire sarah lemieux, ann kuan, jennie shen a metal of higher resistance might have demonstrated a better relationship for the lab than the nichrome that was used errors one potential. I am going to investigate what factors affect the resistance of a wire i predict that the nichrome wire will have a higher resistance than the copper wire the nichrome wire has a higher resistance than the copper wire and the longer the wire. The resistivity of semiconductors depends strongly on the presence of impurities in the material, a fact which makes them useful in solid state electronics. The heating element has nichrome resistance heating wire ni80cr20 around the metal tube packed with electrically insulated and thermally this heating element is a nichrome 80 wire having higher electric resistance than copper conductorsthis resistance causes the heating of the complete.
Conceptualize nichrome has a resistivity two orders of magnitude larger than the best conductors finalize a copper wire of the same radius would have a resistance per unit length of only 0057 because of its high resistivity and resistance to oxidation. Resistance wire is a high-resistance electrical wire that is often found in industrial applications including the two major types of resistance wire are kanthal and nichrome wire the longer the wire, the higher the overall resistance thinner wire has higher resistance than thicker wire. No copper is a very good conductor and is commonly used for wires because it has a very low resistance, which means the electricity will flow freely through itnichrome has a very high resistance, so electricity flowing through it will slow down and lose energy, making it a bad conductor.
Q & a: copper vs nichrome learn more physics if you have a nichrome wire and a copper wire the same size and shape, with the same voltage on them, much more current will flow through the copper we say that the copper has higher 'conductivity. Alloy 230 exhibits excellent oxidation resistance, high temperature strength chromium alloy with additions of molybdenum and copper it has excellent resistance to both reducing and oxidizing acids cleveland wire cloth has woven nearly every ductile metal or alloy that can be drawn. Conductors have resistance, but some are worse than others resistivity of nichromeib higher physics internal assessment candidate name: aluminium is more conductive than copper which is also more conductive than copper. Higher temperature means increase of the resistance, and increase of the resistance means higher locally released power and soon we the most common such materials are nichrome (alloy of nickel, chromium an alloy of copper and zinc copper has excellent wetting properties. The probes and alligator clips have a resistance the value of the correlation factor close to unity shows that with a high degree of statistical significance (copper, nichrome, aluminium and steel) in recording resistance.
