14. The operational amplifier circuit shown in the following figure includes a thermistor. 9 V+ 100 (2 Thermistor 300 (2 1000 The relay must be activated when the thermistor resistance is: A Less than 100 A. B 200 A. C Between 100 and 300 A. D More than 300 A. 15. Decide whether each of these statements is TRUE (T) or FALSE (F). The Wheatstone bridge shown in the following figure is balanced when there is no load on the load cell. R₂ R. L L R3 + A Output Во L R₂₂ OR R₂ Ra HH When the load is applied to the load cell: (i) R₁ increases. (ii) The potential at A is greater than that at B. Which option BEST describes the two statements? A (i) T (ii) T B (i) T (ii) F C (i) F (ii) T D (i) F (ii) F 16. The resolution of an analogue-to-digital converter with a word length of 8 bits and an analogue signal input range of 10 V is: A 39 mV B 256 mV C 1.25 V D 5V 17. Decide whether each of these statements is TRUE (T) or FALSE (F). The ZN439 successive approximations 8-bit ADC has a conversion time of 5 us. It is thus suitable for: (i) Signals without aliasing with frequencies less than 100 kHz. (ii) Giving an output for an input of 2 V with a resolution of 5 µV.
