If θi is the inversion temperature, θn is the neutral temperature, θc is the temperature of the cold junction, then (a) θi + θc = θn (b) θi - θc = 2θn (c) (θi+θc)/(2) = θn (d) θc - θi = 2θn

Answer: (c). The thermo-emf is maximum at the neutral temperature, which lies midway between the cold-junction and inversion temperatures. θn = (θi + θc)/(2). So the answer is (c).

Electrical Power & Heating Effect

If $\theta_i$ is the inversion temperature, $\theta_n$ is the neutral temperature, $\theta_c$ is the temperature of the cold junction, then

Show answer and solution

Answer: (c)

The thermo-emf is maximum at the neutral temperature, which lies midway between the cold-junction and inversion temperatures.
$\theta_n = \dfrac{\theta_i + \theta_c}{2}$ .
So the answer is (c).
