Question 1 Report

A platinum resistance thermometer wire has a resistance of 5 ohms at 0oC and 5.5 ohms at 100oC. Calculate the temperature of the wire when the resistance is 5.2 ohms

80oC

60oC

40oC

10oC

Answer Details

100oC .... 5.5

$θ$ oC .... 5.3

0oC .... 5.0

$\frac{θ - 0}{100 - 0}$ = $\frac{5.5 - 5 .0}{5.5 - 5.0}$

$θ$ = 40oC
