Homework Help: Find the resisitance of the winding at 20/60C

  1. Dec 4, 2008 #1
    Find the resisitance of the winding at 20 and 60 degrees.

    Information given:

    mass: 33.212kg
    Dimensons are: L=551.9291667mm
    W=48mm
    h=144mm
    Volume: 3814934.4mm3
    Number of turns in the winding: 675 diameter of wire = 2.00mm

    The turns can be assumed to be uniformly layered and evenly distributed across the section of the coil. All inter=conducter space is occupied by the insulation and the completed winding can be assumed to fill the winding space.

    The winding material has the following parameters at 20C
    Density: 8740kg/m3
    Resistivity: 1.870E-08ohmM


    If anyone can point me in the direction of the equation(s) i would need to use or just show how u got to the answer i would greatly appreciated :D everyone in the module has been totally stumped on this question so please make me be the first with the correct answer :D

    Ty all!
