Question
Consider the Wheatstone bridge shown in the image. Suppose:
R3 = R4 200 Ω
R2 = variable calibrated resistor
R1 = transducer resistance 40x + 100
-
When x =0, what is the value of R2 required to balance the bridge?
-
If the bridge is operated in a balanced condition in order to measure x, determine the relationship between R2 and x.
