    im doing an experiment in physics titled - how does the diameter of a wire affect its resistance.

    im a bit stuck on the ' factors which may affect my experiment and why ..' bit, can anyone help?

    Ive figured the length of the wire, and its properties any other suggestions?


    Hmmm... off the top of my head....

    - the material the wire is made of
    - how pure the substance the wire is made of is
    - temperature

    I'm sure you can figure out why they effect the experiment.

    Hope that helps
