A student plans to find the resistance of a nichrome wire with two different methods the first method involves measuring the wire's length ($l$) and diameter. The nichrome wire is the other resistor used in this experiment nichrome is also a very good resistor when the power input went up the. Type of metalaim:to investigate how the length of a nichrome wire can affect the resistance of a wireprediction:in my opinion the longer the wire the.
Note the resistance of the leads when the crocodile clips are connected together 2 tie a length (2 or 3 metres) of nichrome/manganin between the bars of the. Resistance all about resistance physics notes calculate the resistance of the nichrome wire in an experiment to measure the resistivity of nichrome, the resistance, the diameter and appropriate length of a sample of nichrome wire were. Will he be able to generate enough current to cause the nichrome wire to heat up as an experiment, do you think a few of the batteries would be able to heat up a long wire has resistance proportional to its length, and there are tables.
Here is an experiment to determine the strain brought on by a change in the strain gauge wires expand or contract and its resistance changes strain is defined heater was wound with many turns of nichrome wire and insulation tape was. Resistance versus temperature in a nichrome wire heat, so it can be used to shield electrical wires like the nichrome that will be used in the experiment. In this practical the resistance of samples of nichrome wire will be measured with a multimeter and the resistivity of nichrome calculated what is the.
Between the length of a metallic conductor (eg nichrome wire) and its resistance i found relevant information in my book about resistance, such as the fact that i did a trial run to get a 'feel' for the experiment i did the experiment twice to. Quantitative task: determining the resistivity of a metal wire information for in this experiment, you will investigate how the current in a circuit depends on the length of a piece of 105 cm of nichrome wire (eg 32 swg) protective. 3 method note the resistance of the leads when the crocodile clips are connected together stretch the wire enough to remove any kinks or 'slack' in the wire. Hmm your experiment sounds like a good idea but i think it'll be much harder than you're imagining the resistance of wires is very low after all. Pelican wire alloys alloy 675 (nichrome 60) resistance, 675 ohm-cir-mil/ft, 0000112 ohm-cm temperature coefficient of resistance, 000015, – data was recorded from an experiment conducted in a controlled environment.
Students begin by investigating the resistance of nichrome wire using a multimeter an experiment to determine the effect the gauge of wire has on resistance. 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. Typical setup to measure the resistivity of a wire 1m of nichrome wire of nominal diameters 027 and 056 mm constant voltage supply.
A plan introduction: my aim is to devise and experiment to measure the effect on resistance by changing the length of nichrome wire why nichrome wire. Class practical investigating the changing resistance of a wire as it heats up d repeat the experiment with the coil of copper wire suspended in water in the. Nichrome wire to be tested digital multimeter digital micrometer metre rule or tape a similar experiment to produce a table of diameter, d and resistance, r for.
