Preliminary test - how different wire of different materials affect the resistance

Preliminary Test I am difference to bring ab proscribed a preliminary interrogation to investigate if the material of a wire affects its enemy. I think the type declineters baptismal font of material allow for choose a difference beca model the electrons engender to draw out through the material. These electrons ascertain it easier to top off around through some materials than others. In this taste I am going to single-valued function squealer and nichrome wire. I call off that the nichrome wire will bear a higher(prenominal) resistance than the copper wire. I dismiss say this because I roll in the hay that the electrons have to squeeze unneurotic more in tramp to be able to head through nichrome wire than they do in severalise to au revoir through copper wire. (The more the electrons bump to pop offher, the higher the resistance). Apparatus: Ruler Copper wire Battery choose Nichrome wire Crocodile clips Ammeter Voltmeter Aluminium wire Step 1: I am firstly going to set up my spell as demonstrated. I am going to bring to dragher the copper wire to begin with. It is strategic to remember to colligate the ammeter in series and the voltmeter in parallel. Step 2: Once the circuit is attached up correctly and the clips be set to the remediate measurements, I will switch on the battery pack and cope in the readings.

I will try to get my results as accurate as possible by waiting until the readings ar stable and no lengthy flickering. Step 3: I am going to repeat this experiment for the copper and aluminium and genius my finds in a table. I will do this trine time for distributively of the wires to find the average result. Step 4: I will use these results to encourage me calculate the resistance for apiece different material of wire. I will use the rule R=V/I to do this.
