Read this essay on resistivity of nichrome come browse our large digital warehouse of free sample essays resistivity of nichrome investigation of the. Nichrome or constantan wire work well (between 28 and 32 swg - the swg rating indicates the cross-sectional area of the wire) other wires can also be used the length is a suggestion only. Physics investigation: aishwarya moothan (2013) conclusion after thorough analysis of the data collected and the graphs derived from data it is seen that the resistance in the wire with the cross sectional area of 0001 (w1) was greater than that in the wire with cross sectional area of 0004 (w2), thus proving my hypothesis correct. Resistance in a wire coursework in this investigation we are resistance of wire essay it does not pass trough as easily in a thin nichrome wire of an.
Length of wire and resistance coursework an investigation into the resistance of a wire - hubpages free gcse physics resistance of a nichrome wire coursework. - 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. An experiment is conducted to measure the electrical resistivity of nichrome in the form of wires with different lengths and cross-sectional areas for one set of measurements, a student uses 30-gauge wire, which has a cross-sectional area of 730 x 10-8 m2.
Nichrome wire data table helps you find the data per different diameters. The purpose of this investigation is to find the relationship, if any, between the temperature of a nichrome wire and that wire's measured resistance hypothesis we believe that increasing the temperature of the nichrome wire will cause the measured resistance of the wire to also increase. Physics experiments record the resistance of the coil of wire using the ohmmeter ammeter, length of nichrome wire v a + 6 v - nichrome wire procedure 1 set.
The resistance r is the resistance wire (constantan nichrorome) that you will be trying to calculate set the power supply to 1v this limits the current through the wire in order to reduce any heating effect which may change the resistivity. We've detected you're using an older version of chrome search service we've detected you're using an older version of chrome. Piece of resistance wire included in the circuit you will then determine the resistivity of the 105 cm of nichrome wire (eg 32 swg) protective resistor.
Which wire had the greater resistance: the thickest or thinnest why must the length of each piece of wire be kept the same in this experiment what other variables did you keep constant in this investigation. Resistivity of nichrome experiment mar 19, 2012 #1 abarrows if i measure the resistance of the wire with a multimeter directly, i get about 2 ohms this is. An investigation into the resistance of a wire free gcse physics coursework essay 100cm nichrome wire method i will stand up during the investigation to. Markedbyteacherscom coursework, essay & homework assistance including assignments fully marked by teachers and peers get the best results here. 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.
An electric space heater has a nichrome heating element with a resistance of 8 o at 20oc when 120 v are applied, the electric current heats the nichrome wire to 1000oc (a) what is the initial current drawn by the cold heating element. Class practical a simple investigation of the factors affecting the resistance of a wire. How does the heating effect of current affect the resistance of a wire for my physics coursework i have to talk about the heating effect of current and what effect it will have on my investigation about the resistance of a wire. Resistance, the current, the voltmeter reading and the resistance of the nichrome wire would change when the rheostat was shifted to increase its resistance four weeks later, 3 pairs of students.
Wire resistance investigation essay introduction title the variables i kept constant to make it a fair test were, the type of wire (nichrome),. 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. Resistance of a wire essaysin this investigation i will carry out an experiment to distinguish how the length of a wire, disrupts the behaviour of the resistance. Essay uploaded by mjb2016 the nichrome wire produces heat rapidly with an electric current due to the high level of electrical resistance that the twisted wire.
Prediction in my investigation i predict that as i change the materials (copper, constantan and nichrome) different readings from the ammeter and voltage will occur, and i expect that copper will have the least resistance of the three materials, followed by constantan, and then nichrome. When investigating this variable, the thickness and material should be kept constant (ie measuring the resistance at different lengths of a nichrome wire at 24 swg) 2) thickness of a wire or cross-sectional area. Category: papers title: investigating the resistance of nichrome essay investigating the resistance of a wire - investigating the resistance of a wire introduction my aim in this experiment is to investigate if the length of a wire affects the resistance of electrons.
