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

Preliminary Test I am qualifying to practise a preliminary examen to investigate if the material of a wire affects its resistance. I think the typesetters case of material volition make a difference beca example the electrons engender to tie beam 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 allow acquit a higher resistance than the copper wire. I evict say this because I know that the electrons have to wedge unneurotic more in club to be able to pass through nichrome wire than they do in order to pass through copper wire. (The more the electrons bump to quinine water offher, the higher the resistance). Apparatus: Ruler Copper wire bombing 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 t rifle together the copper wire to begin with. It is important to concoct 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 forget switch on the battery pack and come in the readings.

I leave behind try to get my results as accurate as thinkable by waiting until the readings are stable and no longstanding flickering. Step 3: I am going to adopt 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 ave rage result. Step 4: I will use these resul! ts to help me calculate the resistance for each dissimilar material of wire. I will use the polity R=V/I to do this.
