resistivity of constantan wire lab report

RESISTIVITY of a wire is the property of the wire, measured in ohmmeter. Length on each reel is approximate.

Resistance = Resistivity x Length of the Wire Cross Section Area of Wire So the resistivity of my wire will be the gradient of my graph. 1 Calculate an average value for the diameter d of the wire. Also you should remember, that this work was alredy submitted once by a student who originally wrote it. The resistance of Nichrome wire is higher than copper wire, with the formula V=IR, the resistance of Nichrome wire is 16.67 ohms and the resistance for copper wire is 0.258 ohms. From the table, the constant for Nichrome is 1.1 x 10^-6 and copper is 1.7 x 10^-8. Also, this unit talks about the transient actions of transmission lines, which are terminated by separate ... friendly form of green energy known as wind power.

EXPERIMENT 16 RESISTANCE AND RESISTIVITY By Eric Pernini, Anthony Sibaja, … Since my early childhood, I have always had passionate and curious about the inner mechanisms of Bonded-Wire Strain Gauges and Introduction of Sensor This paper discusses various sub topics related to the Bonded-Wire Strain Gauges as one of the types of sensors that are used in the industrial processes. 4 0 obj }un�Q(r��z�%� /��mްG��=/�x�t�_���=�-�b@m�������*8�6x�)���?�"�NO8$H��0!�iS CBR�l�K� �{Hj�]�b�+۴��]�kf�k��s���E�b��ꔊK�"/64�d?�-l\zI�W�}�B0d�7�"�����R�6R����@2�-;�F_D��e��C~jrv�Z�‘���}� {����f�~@A�چ�\M�EY4+�4D£x��m�)*Q�Z��_>UI�13��%�a�#w´�@B�A��uBx�y�����̠c�Oy^M9�����Ù���?�����)�^(W! 3.

The most commonly used standards are J, K, T and E. B, S, R and K are used in steel and iron industries. If you can visualize a piece of copper wire with billions of atoms and each one of them losing an electron and all the electrons jumping to other atoms, you will begin to see what current is.Copyright © 2000-2020. Finally, this paper gives a......Q1. I will then plot the graph ofSo the resistivity of my wire will be the gradient of my graph.

5428 Words 22 Pages. 123Helpme.com. Remember that the copper atom has 29 + protons and 29 electrons so if one electron leaves orbit we are left with +29 protons and 28 electrons. Each atom is made up of a nucleus that has a certain number of protons and neutrons with an equal numbers of electrons in orbit. Provide at least 2 sample questions. 3 Determine the gradient of your graph. Show your working. The copper atom has 29 protons in its nucleus with 29 electrons orbiting the nucleus. Lab Report: Testing How the Length of a Wire Determines its Resistance. Which is calculated by the change in x value / by the change in y value.Range of readings = 0.100m 1.000m and 1.000m 0.100m Ammeter Range: +20 to -20, to the nearest 0.01 of a Volt Before adjusting the wire to the desired legnth, leave it to cool for a few seconds to avoid being burntI will take a reading of both current and voltage when the wire is at lengths of 0.100, 0.200, 0.300, 0.400, 0.500, 0.600, 0.700, 0.800, 0.900 and 1.000 m and then backwards in 10 cm intervals so 1.000, 0.900, 0.800, 0.700, 0.600, 0.500, 0.400, 0.300, 0.200, and 0.100.
