Question 6 (a) Explain the working principles of: thermistor. (i) (ii) resistance temperature detector (RTD). (5 marks) (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 52, R₂ = 120 s2, R₂ = 240 52, and R₂ = 100 2. (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 2/°C and R(75°C) = 110.2 2. Determine the RTD resistance if the actual surface temperature is 81°C.
