Q142 / 200 · Manipal (MET) 2011 · Physics

As the temperature of hot junction increases, the thermo emf

A
always increases
B
always decreases
Correct answer
C
may increase or decrease
D
always remains constant

Solution

if the temperature of the hot junction is increased, the thermo e.m.f. may either increase or decrease depending upon the temperature.

Hence, the correct answer is option: 'C'.
