Homework Statement
The bridge circuit below is used to monitor temperature using a thermometer. The thermometer RT has resistance of 100 Ω at 0°C and a linear coefficient with temperature of 0.005 Ω/°C. What is the sensitivity of the bridge (ΔVOUT/ΔT) around 100 °C for ΔT = 1°C? How does it compare with sensitivity around – 100 °C?
Homework Equations
(ΔVOUT/ΔT) = Sensitivity
RT=(1+aΔT)
The Attempt at a Solution
I found out Vout expression but don't know how to differentiate it. Can someone help please?
Vout = (10*Rt/Rt+100) - 5
