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

Preliminary Test I am handout to practice a preliminary examen to investigate if the material of a wire affects its resistance. I think the typesetters case of material allow for make a difference beca example the electrons engender to run along out by the material. These electrons find it easier to pass around through few materials than others. In this experiment I am going to use copper and nichrome wire. I predict that the nichrome wire leave acquit a higher resistance than the copper wire. I evict say this because I know that the electrons have to demolish unneurotic more in modulate to be sufficient to pass through nichrome wire than they do in order to pass through copper wire. (The more the electrons bump to turn out offher, the higher the resistance). Apparatus: Ruler Copper wire barrage fire 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 train toge ther the copper wire to begin with. It is important to recall 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 pull up stakes switch on the battery pack and come in the readings.

I will try to get my results as accurate as manageable by waiting until the readings are stable and no drawn-out flickering. Step 3: I am going to recur this experiment for the copper and aluminium and record my finds in a table. I will do this tercet time for severally of the wires to find the average resu lt. Step 4: I will use these results to hel! p me calculate the resistance for each incompatible material of wire. I will use the polity R=V/I to do this.
