Which of the following quantity is measured by Thermister?(a) pressure

1.	Which of the following quantity is measured by Thermister?(a) pressure(b) displacement(c) temperature(d) heightI got this question in class test.My doubt is from Essential Parameters for Telemedicine topic in chapter Telemedicine Technology of Biomedical Instrumentation
Answer» CORRECT ANSWER is (c) temperature The explanation: Thermistors are the OXIDES of certain metals like manganese, cobalt and nickel which have large negative temperature coefficient, i.e. resistance decreases with increase in temperature. A thermistor is used to measure temperature. It is a temperature transducer. With a change in temperature its resistance CHANGES. Thus its WORKING principle is variable resistance.
