A strain gauge with a 40cm wire length and a 25µm wire diameter has a resistance of 250Q and a gauge factor of 2.5. Analyze the change in wire length and diameter when the resistance change is measured as 0.50. Assume that the complete length of wire is positive strain.

Explain what is happening?

hello, please answer the following question a,b,c and d. please make sure you understand the question and dont forget the signs (positive or negative. show each step clearly. thank you. R2 2.2 kn R1 C 1 kN 82 nF VOUT VIN Figure 2: Differentiator Circuit 2. For the differentiator circuit above calculate: a. Break Frequency fb = b. Voltage Gain V ou/Vin at 10fb (a decade above fo). c. With Vin = 0.5 Vpk (f = 5 kHz) calculate Vout p = d. If Vin is a triangular voltage source, what is expected waveshape of Vout?

Need some help with this amplifier question
