Homework Help: Quarter- bridge strain gauge circuit

  1. May 11, 2008 #1
    Could anybody help me please? :cry

    If I have quarter- bridge strain gauge circuit, where strain gauge will have its initial resistance and i will add another 3 resistors, 1 on the same side like strain gauge, and another 2 on the opposite side, so I will balance circuit and my voltmeter reading will be zero.
    With effect of increasing temperature , resistance on strain gauge will increase, how could i get the values? Please help me someone because I am thinking about it already two days and i am lost.

    I have no idea what equation to use...:confused:
