Question

Consider the following statements (A) and (B) and identify the correct answer given below :
(A) : Peltier coefficient is numerically equal to the potential difference across the junctions of the thermocouple through which current is flowing.
(B) : According to Thomson, energy is neither absorbed nor evolved at the junction of a thermocouple but is absorbed or evolved only along the lengths of both the conductors.

• A. Both A and B are true
• B. Both A and B are false
• C. A is true but B is false
• D. A is false but B is true

Answer 1

The correct option is C A is true but B is false

(A) Peltier coefficient is numerically equal to the potential difference across the junctions of thermocouple through which current is flowing

This statement is true

(B) According to Thomson, energy is neither absorbed nor evolved at the junction of thermocouple but is absorbed or evolved only along the length of both the conductors

This statement is false energy is absorbed or evolved at the junction.
