## RESISTANCE OF CONSTANTAN WIRE COURSEWORK

### RESISTANCE OF CONSTANTAN WIRE COURSEWORK

Constantan is a Nickel-Copper based alloy wire that has a high resistivity and is mainly used for thermocouples and electrical resistance heating. Measure the diameter of each wire using a micrometer and then measure their lengths in metres. Electrical resistivity Nichrome and Constantan are often used as resistance wire. However, due to my line of enquiry, I will only change the length of the wire. Below is a table of my results Table 3. File – I Love Physics Forever! I will repeat this method every 5cm until I get up to cm, taking three readings from both the voltmeter and ammeter each time to ensure accuracy.

A metre-bridge circuit, in which the unknown resistance consists of a length of constantan wire , is connected up as in Fig. Complete a table a suitable table and calculate the resistance of the wire for each length. The resistance of a piece of wire is dependant on its length, cross-sectional area and the type of metal the wire is made of. Variables There are different variables that can be changed in this experiment; these are the independent variable. Non-consent will result in ComScore only processing obfuscated personal data. I will also control, using the power pack, how many volts pass through the wire. I think my method could have been improved to produce results that were even more consistent.

You can courseworkk this to streamline signing up for, or signing in to your Hubpages account. Table 3 shows that as the length of the wire increases, the resistance increases, as well.

Therefore the length will be an independent variable and all of the other variables we will try to keep the nbsp; Free constantan wire Essays and Papers — of a Constantan Wire is Affected by Its Length — Investigating how the Resistance of a Constantan Wire is Affected by Its Ccoursework Introduction: Look in the table for material resistivity for commonly used materials. They are available 24 hours each day, 7 days per week, through email, online chat or by mobile.

Introduction I am going to investigate how the two methods of acquiring the resistivity of constantan will compare to each other with its results and compare that to the actual constabtan of resistivity of constantanthen by getting nbsp; Experiment Coirsework Measure The Resistivity Of A Wire — Cyberchalky!

# Experiment To Measure The Resistivity Of A Wire

There are different variables that can be changed in this experiment; these are the independent variable. This is because the free electrons in the wire bump into more atoms, thereby making it harder for electricity to flow.

The resistivity of Constantan. The free electrons keep bumping into atoms. Accessed May 23, L Length of wire. Add this document to collection s. Discussion Overall, my results are very consistent with my predictions. In this experiment I predict that the longer the length of wire the greater the resistance.

Glad I could help! How about make it original? The resistivity of Constantan Paper.

Class practical A simple investigation of the factors affecting the resistance of a wire. A resistance wire AB of uniform cross section, usually one meter in length, is mounted on a board with auxiliary components neces nbsp; A-level Physics Test Unit 03T — P14 ISA June — AQA was performed to investigate how the resistance of a length of constantan wire varies with the diameter of the wire. Javascript software libraries such as jQuery are loaded at endpoints on the googleapis.

Anyway, for those who don t know, the resistivity of constantan. Using the rheostat alter the number of volts running through the circuit until approximately 3 amps is reached. I used some of the data for my physics homework so thanks for that. OK doing some physics coursework at the moment where I have to measure the resistivity of Constantan.

Sorry, but downloading is forbidden on this website. Similarly, the shorter the wire, the smaller the resistance because iwre will be fewer atoms for the electrons to bump into, thereby easing the flow of electricity.

Registration form – asian pacific association for study of the liver. I will also control, using the power pack, how many volts pass through the wire. As others have noted, the big issue is getting the resistance of the wire into the range where your multimeter can essay writer program measure it accurately.

However, I made sure that the wire remained straight throughout the experiment.
