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.
