Investigating the resistance of nichrome essay so too did the resistance of the nichrome wire, proving our prediction was correct and accurate as the length of the nichrome wire doubled, so too did the number of electrons within the wire, giving a higher resistance. My hypothesis was correct the nichrome wire proved that the longer the wire, the higher the resistance ohm's law states that the current flowing through the circuit is directly proportional to the voltage applied. The longer the nichrome wire is, the larger the resistance will be this was certainly the case here as the resistance for the 1 metre wire was more than double that of the 0 5 metre wire this larger resistance would be due to the cross-sectional area of the wires.
Aim the resistance of a conductor is well known to be dependent upon the material it is made from, its length, diameter, and temperature i am going to be studying the resistance of wire to see how a length of nichrome wire affects the dependent variable, 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. For the conclusion i would like to state that for every 5cm decrease in the length of nichrome wire, the voltage decreases by approximately 01 v, whilst the resistance decreases by approximately 07 (from 45-40cm), followed by 06 (from 40-35cm), followed by 05 (from 35-30cm.
Resistance of a wire task the resistance of a wire depends on factors, one of which is the length of the constanton wire, i will be investigating this into more detail. Nichrome 80 has a maximum operating temperature of 1180°c (2150°f) it has good corrosion resistance, good oxidation properties, and very good form stability. Set up a series circuit with the ammeter, switch, nichrome wire resistor (figure 1), light bulb (figure 2) connected in a series and connect the voltmeter in parallel with the nichrome wire or light bulb resistor.
Year 12 physics eei: factors affecting electrical resistance uploaded by phillip soalheira an extended experimental investigation done in year 12 (high school), looking at physical factors that affect the electrical resistance of various objects. Home free essays factors affecting the resistance of a wire factors affecting the resistance of a wire essay b pages: we will write a custom essay sample on factors affecting the resistance of a wire specifically for you for only $1638 $139/page to investigate how the length of a nichrome wire can affect the resistance of a wire. Question a portion of nichrome wire of radius 260 mm is to be used in winding a heating coil if the coil must draw a current of 990 a when a voltage of 120 v is applied across its ends, find the following. Lightning vapes nichrome 80 resistance wire is perfect for rebuilding your atomizer, and especially good for sub ohm coil builds it has a lower resistance per length compared to kanthal, which means that it will heat up noticeably faster and is a preferred alternative to kanthal for many cloud chasers for this reason. Nichrome 60 wire is generally used to manufacture electrical resistance for insulated and open appliances it is widely used in the application of industrial furnaces and even provides the means to melt metals.
Secondly i shall vary the length of the wire while keeping the diameter of wire (30 cm) and type of wire as fixed variables, in order to investigate the effect of wire length on the resistance. Resistance of wire essay length of wire is fixed to a one meter ruler the first crocodile type of metal aim: to investigate how the length of a nichrome wire can affect the resistance of a wire prediction: in my opinion the longer the wire the more resistance there will be. - resistance of a wire investigation aim: to investigate the effects of resistance on a nichrome wire planning my planning will begin with providing a background understanding on the theory of resistance and how it participates in the overall process of the electric current. Nichrome, a non-magnetic alloy of nickel and chromium, is commonly used to make resistance wire because it has a high resistivity and resistance to oxidation at high temperatures when used as a heating element, resistance wire is usually wound into coils.
Rba depot is the leading supplier for resistance type wires including kanthal, nichrome, nickel, titantinum, stainless steel, clapton, fused, alien, tiger, hive free shipping on all orders in the usa. The physical resistance nichrome wire coursework develop strong thesis statement properties of transition metals like density, melting points, boiling points, strength are described and discussed along with a description of the. Coiled nichrome wire (open coil resistance wire elements - infrared and air process/duct heaters) 5, 10 or 30 pound spools of nichrome or kanthal nichrome wire is commonly used as a resistance heater for cutting foam (styrofoam, polyurethane, etc) fabrics, and a variety of other materials. The resistance of wire is one of the most popular assignments among students' documents if you are stuck with writing or missing ideas, scroll down and find inspiration in the best samples resistance of wire is quite a rare and popular topic for writing an essay, but it certainly is in our database.
Task to investigate how the resistance of a wire is affected by the length of the wire theory what is resistance resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. – nichrome wire conducts electricity very well and because current is the movement of atoms through the wire, if the wires length is doubled so is the number of electrons which will double the resistance. To investigate the factors of affecting the resistance of a wire essay sample aim: to investigate the factors of affecting the resistance of a wire in this experiment i will be using a metal nichrome wire to show the resistance when the length and width is changed.
Experiment: ohmic resistance and ohm’s law patrick doan mr sadowsky 11 phys 71 12/9/08 table of contents the nichrome wire is the other resistor used in this experiment nichrome is also a very good resistor essay on resistance of a wire 1877 words | 8 pages. A carbon wire and a nichrome (solved) november 17, 2013 a carbon wire and a nichrome wire are connected in series, so that the same current exists in both wires if the combination has a resistance of 10 0 k' at 0 °c, what is the resistance of each wire at 0 °c so that the resistance of the combination does not change with temperature.
