Question 2 (Cont'd.) e) The circuit below (Figure 2.1) and the calibration curve (Figure 2.2) can be used for temperature measurement. Figure 2.1 1200- 1100- 1000- resistance/ 900- 0 10 20 30 temperature/C Figure 2.2 Suppose R1 = 10K2, R2=142 and R3=112 (the value of variable resistor). What is temperature of the thermistor?
