Question

5) We would like to measure a 10 ohm resistor using a 100 kohm reference resistor. The excitation voltage ($V_{ex}$) is 1 V. We know that the number of bits in the analog to digital converter (ADC) is 16. Considering the ADC, what is a proper value for the full scale range voltage ($E_{FSR}$)? a) 10 V b) 5 V c) 1 V d) 0.5 V 6) A Platinum RTD is used to determine the temperature of a boiler. The RTD is used in a voltage divider circuit to determine the temperature of the boiler. The reference resistor is 100 ohm and the excitation voltage is 1 V. If the voltage drop across the RTD in the voltage divider circuit is 0.5 V, what is the temperature? The RTD is 25 ohm at 0 $^\circ$C and the thermal expansion coefficient of the Pt is 0.0039 1/$^\circ$C. a) 256 $^\circ$C b) 125 $^\circ$C c) 0 $^\circ$C d) None of these 7) In the straingage experiments, we adjusted a knob to manually balance a Wheatstone bridge. The knob was, in the setup, part of a, a) A potentiometer b) A straingage c) A bridge arm d) none of these
