    Every Wheatstone bridge consists of four elements or arms.
    Three of the arms can be ordinary resistors while the active element is the remaining arm.

    An active strain gauge is mounted in such way that it react to the force applied to the sensor. A passive element will not react then force is applied to the sensor. But it may have a role like to compensate for temperature. As an aside working with "bare" strain gauges require quite a lot of knowledge an experience. Like bonding them correct onto the sensor/object. It is not beginner level in any way. If you try to create say your own full-bridge type III configuration setup the result will most probably not be very good
