The temperature of the cold junction of thermocouple is 0^ C and the temperature of hot junction is T^ C . The emf is E=16 T-0.04 T^2 V . The inversion temperature T_i is

Options

  1. A300^ C
  2. B200^ C
  3. C500^ C
  4. D400^ C

Correct answer

D. 400^ C

Step-by-step solution

As, E=16 T-0.04 T^2 At inversion temperature, E=0 aligned 16 T-0.04 T^2 & =0 T_i & = 16 0.04 =400^ C aligned
