AS PHYSICS PRACTICAL COURSEWORK RESISTANCE OF NICHROME WIRE PLANNING: The experiment that I am going to carry out involves largely aspects to do with resistance. In this particular experiment I will test how the resistance varies across a piece of nichrome metal wire over a range of distances. I will try to find out if there is a relationship between resistance and length. To determine whether or not there is a relationship between the length of a wire and the resistance, I will measure the current flowing through different lengths with a certain voltage and work out the resistance using R=V/I. I will also attempt to find a relationship between resistance and thickness. I believe that this will result in a straight line as well because R?1/A. So, as thickness increases resistance should decrease, as the electrons should be able to flow more easily. Therefore, current should increase with increasing thickness. WHAT I WILL DO The ammeter and...
