Wheatstone Bridge

    1. The problem statement, all variables and given/known data
    I think I got part A. I'm complete lost with b -d and help would be great


    2. Relevant equations

    3. The attempt at a solution
    It think part d is ∆V = [(∆R1 - ∆R2 + ∆R3 –∆R4 ) / 4R ] * Vo But I'm not sure

    See if this explanation helps - http://en.wikipedia.org/wiki/Wheatstone_bridge

    In parts b-d, R4 = R + [itex]\Delta R[/itex], and R1 = R2 = R3.

    Find an expression for V0 in terms of R1, R2, R3 and R4, then substitute in the appropriate values.

    In part d, one is looking for how much V0 changes as [itex]\Delta R[/itex] changes.
