Preliminary Test
I am going to perform a preliminary test to investigate if the material of a wire affects its resistance.
I think the type of material will make a difference because the electrons have to pass through the material. These electrons find it easier to pass through some materials than others. In this experiment I am going to use copper and nichrome wire. I predict that the nichrome wire will have a higher resistance …

…waiting until the readings are stable and no longer flickering.
Step 3: I am going to repeat this experiment for the copper and aluminium and record my finds in a table. I will do this three 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 different material of wire. I will use the formula R=V/I to do this.
