For which one of the following measurements a thermistor can be used? Correct Answer Percent of CO<sub style="">2</sub> in air

A thermistor (or thermal resistor) is defined as a type of resistor whose electrical resistance varies with changes in temperature.

Thermistors have a variety of applications. They are widely used as a way to measure temperature as a thermistor thermometer in many different liquid and ambient air environments.

  • Digital thermometers (thermostats)
  • Automotive applications (to measure oil and coolant temperatures in cars & trucks)
  • Household appliances (like microwaves, fridges, and ovens)
  • Circuit protection (i.e. surge protection)
  • Rechargeable batteries (ensure the correct battery temperature is maintained)
  • To measure the thermal conductivity of electrical materials
  • To measure the percent of CO2 in air
  • Temperature compensation (i.e. maintain resistance to compensate for effects caused by changes in temperature in another part of the circuit)
  • Used in Wheatstone bridge circuits

Various measurements are made on an NMOS amplifier for which the drain resistor RD is 20 kΩ. First, DC measurements show the voltage across the drain resistor, VRD, to be 2 V and the gate-to-source bias voltage to be 1.2 V. Then, ac measurements with small signals show the voltage gain to be −10 V/V. What is the value of Vt for this transistor?
