Question

Derive a resistive deflection bridge suitable for strain measurement using the strain gauge with factor G=2.0, Unrestrained resistance R0=120 Ohm and temperature sensitive to the ambient temperature. The current through the sensor must not exceed 1 mA. Motivate your design choices clearly. Plot the output voltage of the deflection bridge for various choices of the component values in the bridge, illustrating the effect of your design choices.
