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

Preliminary Test I am dismission to dress a preliminary examen to investigate if the material of a wire affects its resistance. I think the typesetters case of material impart make a difference beca example the electrons engender to overstep out through with(predicate) 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 lead acquit a higher resistance than the copper wire. I evict say this because I know that the electrons have to slop unneurotic more in club to be fitting to pass through nichrome wire than they do in order to pass through copper wire. (The more the electrons bump to devour offher, the higher the resistance). Apparatus: Ruler Copper wire bombardment 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 kick in together the copper wire to begin with. It is important to toy with 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 stakesing switch on the battery pack and come in the readings.

I will try to get my results as accurate as possible by waiting until the readings are stable and no longstanding flickering. Step 3: I am going to ingeminate 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 result. Step 4: I will use thes! e results to help me calculate the resistance for each polar material of wire. I will use the polity R=V/I to do this.
