From other experiments, it is found that the resistance of a thermistor varies according to the equation R = Roe/ (1) Where Ro and B are constants and T is the absolute temperature. From two measurements of the resistance at the (known) steam points and ice points, the above equation can be used to determine B and Ro. Taking the natural logarithm of both sides, one can see that в T (2) In(; Ro Prior to lab class, use R1 at T1 and R2 at T; in equation (1) and derive expressions for Ro and B. Show all of the algebra and include the derivation in the theory portion of your lab report. The expression for B is
