Homework Help: Impedance of an inductor

  1. Oct 12, 2009 #1
    1. The problem statement, all variables and given/known data
    Two inductive elements that are wired into a Wheatstone bridge. Upon displacement of the sensor, each inductor will change by delta L one increasing, the other reducing.
    What is the equation for the impedance of an inductor?
    Determine an expression for the ratio of the input (vi) and output (vo) AC voltages in terms of the ratio delta L/L

    2. Relevant equations

    3. The attempt at a solution

    Hi Bertrodriguez, welcome to PF!:smile:

    As per forum rules (which you agreed to when you signed up for your account!), you must provide some attempt at a solution, or at least explain where you are stuck. We are not here to do your homework for you.

    If you haven't already done so, I'd begin by reading the sections of your text on inductors and impedance, and then write down the equation for impedance...
