    You need to say what you are doing , what you are stuck on, and what help you need.

    I'm doing the resistivity of a material and I just want to know when writing the case study do I write on the resistivity of a particular material for eg constantan or is it just resistivity in general.Thank you

    is this a practical investigation? or is this a sort of, informative document telling the reader about material properties?

    If it's the former, you should be talking about the resistivity of the materials being used in whatever experiment you are doing.

    If its the latter, then you'll want to compare the resistivity of different materials and say why they have different resistivities. the key lies in their atomic structure

    thank you for your response.It is a practical investigation so that means I should be taking up a particular material.Is it still ok if I get a 5%error off the actual resistivity value of a particular material from my practicals?

    Should be absolutely fine. If you're calculating the values of resistivity, then you will get extra marks if you talk about the uncertainty of values you calculate and why they arise. then you can go onto talk about how you could minimize that uncertainty if you were to repeat the experiment in the future (e.g. using lightgates for timing instead of a stopwatch)
