(b) Given a Wheatstone bridge as shown in Figure 2, derive the offset voltage, AV. Determine the value of AV if V = 1 volt, R₁ = 120 £2, R₂ = 120 52, R₂ = 240 52, and R4 = 100 52. (3 marks) (c). A RTD was applied to a hot body surface to obtain the temperature reading. Knowing that the fractional change in resistance per degree of temperature (a) is 0.001875 22/°C and R(75°C) = 110.2 2. Determine the RTD resistance if the actual surface temperature is 81°C. (2 marks) R₁ R2 V ΔΙ R3 Figure 2: Wheatstone bridge R4
