A platinum resistance thermometer wire has a resistance of 5 ohms at 0
oC and 5.5 ohms at 100
oC. Calculate the temperature of the wire when the resistance is 5.2 ohms
-
A.
80oC
-
B.
60oC
-
C.
40oC
-
D.
10oC
Correct Answer: Option C
Explanation
100oC .... 5.5
\(\theta\)oC .... 5.3
0oC .... 5.0
\(\frac{\theta - 0}{100 - 0}\) = \(\frac{5.5 - 5 .0}{5.5 - 5.0}\)
\(\theta\) = 40oC
