A resistance temperature detector (RTD) is placed in a Wheatstone bridge as according to Figure 4 . The RTD can be assumed to have 1st order dynamics where the temperature co-efficient is given as: γ=0.001K−1. It is given that when R1=500Ω,R2=600Ω,R3=300Ω, the Wheatstone bridge is balanced when T=280K. The input voltage is also given as: V=8 Volts. 1. Please find the RTD resistance under the balanced condition. Subsequently, determine the output voltage Vo of the Wheatstone bridge when T=340K. (8\%) 2. Suppose the temperature co-efficient has an uncertainty tolerance of 3% and the voltage source V has an uncertainty of \pm 0.1 Volts. The other components of the circuit do not contain any uncertainty. Please determine the resulting uncertainty of Vo when T=340K. (7%) Figure 4
