since ∆R/∆T is constant, you want
T such that
(T-0)/(9.61-10.4) = (100-0)/(10.71-10.4)
and R such that
(45-0)/(R-10.4) = (100-0)/(10.71-10.4)
A platinum resistance thermometer measures temperature on assumption that the change in the electrical resistance of platinum is proportional to the change in temperature. The resistance of the platinum wire at O°c is 10.4π and 10.71π at 100°c. Calculate the temperature when the resistance is 9.61π. What will the resistance of the wire when the temperature is 45°c
