Refer to Problem 8.5. If the voltage and current (in amps) for three pairs of measurements are (V.I) = (-5.2,-0.50), (0.3,0.00), and (5.5,0.50), what is the resistance (in ohms) inferred from Ohm's law for these three measurements? What is the uncertainty in the resistance? 8.5. ** Line Through the Origin. Suppose two variables x and y are known to satisfy a relation y = Bx. That is, y x x, and a graph of y vs x is a line through the origin. (For example, Ohm's law, V = RI, tells us that a graph of voltage V vs current I should be a straight line through the origin.) Suppose further that you have N measurements (x;, yi) and that the uncertainties in x are negligible and those in y are all equal. Using arguments similar to those of Section 8.2, prove that the best estimate for B is %3D

The relation between resistance R and temperature T for a thermistor (a device that measures temperature) closely follows R = Ro e[Beta (1/T - 1/To)] where R is the resistance in ohms measured at temperature K, and Beta is a material constant. What are the units of Beta and Ro? Clearly show how you decided on your answer.
For temperature-dependent ohmic resistors (at least the kind we're focusing on), the relationship between resistance & temperature is linear. With that in mind, compare the formula for temperature-dependent ohmic resistance to the equation for a line (y = mx + b) and determine the slope and the y-intercept for a graph of R vs. T. Your answers should be in terms of Ro, ?, & To. [NOTE: for Ro & To the subscript is a lowercase o] R = Ro[1 + ?(T − To)] slope = y-intercept =
