Question

The resistance of a resistance thermometer has values 2.71 and 3.70 ohm at 10oC and 100oC. The temperature at which the resistance is 3.26 ohm is:

Solution

Correct option is

50oC

 

Change in resistance 3.70 – 2.71 = 0.99  corresponds to interval of temperature 90oC.

So change in resistance 3.26 – 2.71 = 0.55  corresponds to change in temperature
