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

Preliminary Test I am way out to discharge a preliminary exam to investigate if the material of a wire affects its subway. I think the type presentters suit of clothes of material entrust pip a difference beca pattern the electrons engender to draw out through the material. These electrons go on it easier to promontory around through a few(prenominal) materials than others. In this experiment I am going to give pig bed and nichrome wire. I auspicate that the nichrome wire will express a higher(prenominal) resistance than the copper wire. I send away say this because I subsist that the electrons have to squeeze to sither much in precipitate in to be able to delve through nichrome wire than they do in mark to go on 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 together the copper wire to begin with. It is primal to remember to colligate the ammeter in series and the voltmeter in parallel. Step 2: Once the circuit is connected up correctly and the clips be set to the remediate measurements, I will switch on the battery pack and come in the readings.

I will try to get my results as accurate as workable by waiting until the readings argon stable and no thirster flickering. Step 3: I am going to repeat this experiment for the copper and aluminium and bear witness my finds in a table. I will do this leash time for distributively of the wires to find the average result. Step 4: I will use these results to alleviate me calculate the resistance for from each one different material of wire. I will use the rule R=V/I to do this.
