A platinum resistance thermometer records 3.0\(\Omega\) at 0oC and 8.0\(\Omega\)...

Question

A platinum resistance thermometer records 3.0\(\Omega\) at 0oC and 8.0\(\Omega\) at 100oC. If it records 6.0\(\Omega\) in a certain environment, The temperature of the medium is

Options

A) 80oC

B) 60oC

C) 50oC

D) 30oC

The correct answer is 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
