A platinum resistance thermometer records 3.0\(\Omega\) at 0
oC and 8.0\(\Omega\) at 100
oC. If it records 6.0\(\Omega\) in a certain environment, The temperature of the medium is
-
A.
80oC
-
B.
60oC
-
C.
50oC
-
D.
30oC
Correct Answer: Option B
Explanation
8\(\Omega\).....100oC
6\(\Omega\).....\(\theta\)oC
3\(\Omega\).....0oC
\(\frac{6 - 3}{8 - 3}\) = \(\frac{\theta - 0}{100 - 0}\)
therefore, \(\theta\) = 60oC
