A. v=-(△R×Vdc)/(2×R+△R)
B. v=-(△R×Vdc)/2×(R+△R)
C. v=-Vdc/[2×(2×R+△R)]
D. v=-(△R×Vdc)/ [2×(2×R+△R)]
Answer:A

Explanation: If the Ra=Rb=Rc=RT=R(Equal), then the output voltage across the bridge terminals of the transducer bridge is v=-(△R×Vdc)/ [2×(2×R+△R)]. 6. Which type of thermistor is chosen for temperature measurement and control?
