(b) A calibration of an NTC thermistor is performed by measuring the resistance at five different temperatures:- Temperature Resistance (deg C) (Kiloohms) 30 18.5 35 15.5 37 14 5 39 13.7 45 11.2 Using the data given in the table, find the value of Beta for the NTC thermistor You should use a graphical package (e.g. Excel or MatLab) to find the most precise value of Beta. Explain your methods throughout [16 marks] (c) The thermistor (above) produces a resistance equal to 13.2 Kiloohms, when measuring the temperature of a patient Calculate the temperature of the patient."
