    Hello!
    I have used Quarter bridge using strain gauge whose nominal resistance is 350ohm and Gauge factor is 2.13+1%. The bridge is excited by 1KHz,1V(p-p) sine wave signal. The bridge output for DC excitation is Vout=(Vin/4)ΔR/R.Is the same formula for AC excitation? Please give the correct answer.

    It is considered rude to hijack someone's thread. Now you have your own.
