QUESTION 1

Please answer correctly. Please show all the necessary steps

Thermistor 1 The thermistor is a commonly used device in many commercial, consumer, and industrial products. A thermistor with a negative temperature coefficient has a characteristic where its resistance is exponentially negative in proportion to temperature and takes on the form 5 V for some constants Ro, ß and To. A thermistor, Rx, is placed in a voltage-divider interface circuit to monitor the temperature of a chamber as shown with the following parameters: B = 3500 K To 25 °C (25+273 K) Ro = 33 ΚΩ R, = 39 ΚΩ = R Check R₁ RX(T) = Roe VOUT (7-7) ◆ and so the output voltage would In this configuration, as the temperature increases, the resistance of the thermistor At a particular instant on a day, the output voltage was measured to be 2 V. Determine the resistance of the thermistor, and hence temperature of the chamber in kelvins. ΚΩ Rx T K ◆
