Homework Help: Diameter and length of wire

  1. Jul 28, 2009 #1
    1. The problem statement, all variables and given/known data
    if the diameter of wire is doubled will there be any change in length of wire

    2. Relevant equations

    3. The attempt at a solution

    I wouldn't think so. The length and width are independent directions, so changing one will not affect the other. But with things such as volume or resistance that depend on the the diameter, this will not be the case.

    Re: electricity

    There is much missing from this post. Most notably, sections 2 and 3 are completely blank.

    Also, I suspect there is more to this question. For example, perhaps the volume of the wire is to remain constant ... or the length or surface area? Or, perhaps some electrical property (judging from the thread title) is to be held fixed?

    Without that information, it is impossible to answer this question.
