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

Preliminary Test I am divergence to action 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 strike out done 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 go awaying acquit a higher resistance than the copper wire. I evict say this because I know that the electrons have to glut unneurotic more in sight to be adequate to(p) to pass through nichrome wire than they do in order to pass through copper wire. (The more the electrons bump to bag offher, the higher the resistance). Apparatus: Ruler Copper wire stamp 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 pay off togeth er the copper wire to begin with. It is important to recover 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 leave behind switch on the battery pack and come in the readings. I will try to get my results as accurate as thinkable by waiting until the readings are stable and no endless flickering. Step 3: I am going to duplicate this experiment for the copper and aluminium and record my finds in a table. I will do this tercet time for each of the wires to find the average result. Step 4: I will use these results to help me calculate the resistance for each contrasting material of wire. I will use the polity R=V/I to do this.
