Question: A . ) When no effect is applied to the strain gauge in the bridge circuit in the figure, its resistance is 1 2 0

A.) When no effect is applied to the strain gauge in the bridge circuit in the figure, its resistance is 120 and its Gauge Factor is 2. Calculate the voltage Ec when its length increases from 20 mm to 20.1 mm with applied force. (All Rs in the circuit are 120 ohms. The variable resistance is strain gauge.)30P
B.) What can be done to double the voltage received from Ec in the same system? 10P
