In case of thermistor, which one of the following statements is 'WRONG'? (a) Resistance of NTC thermistor decreases with increase in its temperature. (b) Resistance of PTC thermistor decreases with increase in its temperature. (c) NTC thermistors are commonly used as temperature sensors. (d) PTC thermistors are generally used as resettable fuses.

Answer: (b). NTC: resistance decreases as temperature rises; used as temperature sensors. (a), (c) correct. PTC: resistance increases as temperature rises; used as resettable fuses. (d) correct. (b) says PTC resistance decreases with temperature, which is wrong. So the answer is (b).
