A thermocouple thermometer is connected to a millivoltmeter which can read up to 10mV. When one junction is in
ice at 0°C and the other is steam at 100°C, the millivoltmeter reads 4mV. What is the maximum temperature which
this arrangement can measure

The maximum temperature which this arrangement can measure is 250-degree celsius.      

Explanation:

The maximum temperature which this arrangement can measure is 250-degree celsius.

Given:

Reading millivolts =10 mv that is 10 millivolts

One junction is in ice at 0-degree celsius

Other is steam at 100-degree celsius. After that millivolt reading is 4 mv.

Let t1 be 10 millivolts and t2 be 4 millivolts.

To Find:

The maximum temperature t

Formula:

t= t1/t2*100

Solution:

t= t1/t2*100

t= 10/4*100

t = 250°C

Therefore the maximum temperature which this arrangement can measure is 250-degree celsius.
