    basic factiors: Length, Width, resistivity of the wire.

    Comes from this formulae:


    R= pL/A

    R = resistance
    p = resistivity
    L = length
    A = surface area

    We've covered this in Physics

    A is cross-sectional area.

    I did this coursework, all you really have to do is read up about it and get to know how electricity works and the crystal matrice or something, and stuff about pd and stuff... (hehehe that's a lot of 'stuff') read through your textbook and revision book if you have one...

    Yes, thats what I meant, therefore you needed to know the width of the wire ie radius,
