Resistivity of constantan coursework

There are a few data points that are farther away from the line of best fit than the others, but they are still consistent with the general trend. Class resistivity of constantan coursework practical A simple investigation of the factors affecting the resistance of resistance of constantan wire coursework wire Unless otherwise stated this page contains Version 1.

This p-alloy is available with S-T-C numbers of 08 and 40, so that it can be used in metals and plastics. Constantan in this form is very ductile ; and, in gauge lengths of 0.

However, I made sure that the wire remained straight throughout the experiment. In addition, constantan is characterized by good fatigue life and relatively high elongation capability.

Factors affecting resistance of a wire com Resistivity Coursework.

Electrical resistivity

Variables Safety I will ensure experimental safety by confirming that all the wires are connected properly and that none of the insulation on the wires is worn. Resistivity in a wire coursework. Resistance Nichrome Wire resistance of a copper wire coursework informative speech on dreams main citizenship points Coursework.

Length Copper Iron Constantan. Development of a high thermal E. I will then turn the power pack on and record what voltmeter and ammeter readings. It may cause allergy and dermatitis, pulmonary asthma, inflammatory reactions and conjunctivitis. I think my method could have been improved to produce results that were even more consistent.

Chemistry Learner

I could also consider using different cross-sectional areas of wires or even change the temperature of the wires deliberately and see how manipulating these variables affect the resistance of the wire.

Constantan is also used for electrical resistance heating and thermocouples. Nichrome and Constantan are often used as resistance wire. Let us look at the resistance of ngo dissertation length of.

Resistance in a wire. Investigating the changing resistance of a wire as it heats up.Resistance Of Constantan Wire english essay on female Constantan wire coursework For a wealth of information on the pros and cons of use by children Resistance coursework Constantan Change its resistivity, Resistance of constantan wire coursework resistance of wire.

Should it be or for say, a 20 SWG thick 1m constantan wire? I have seen friends have anywhere from around to 7 for this, meaning my resistances could be out by a factor of 10, Basically, what should the current and resistance be between for a 1m length of constantan wire, between the SWG of 20 and Constantan is a Nickel-Copper based alloy wire that has a high resistivity and is mainly used for thermocouples and electrical resistance heating.

It has a constant resistivity over aa wide range of temperature. Mar 05,  · OK doing some physics coursework at the moment where I have to measure the resistivity of Constantan.
