MCQ
Consider the following two statements:
  1. Free$-$electron density is different in different metals.
  2. Free$-$electron density in a metal depends on temperature.
Seebeck effect is caused
  • ✓
    Due to both $A$ and $B.$
  • B
    Due to $A$ but not due to $B$.
  • C
    Due to $B$ but not due to $A$.
  • D
    Neither due to $A$ nor due to $B.$
✓

Answer

Correct option: A.
Due to both $A$ and $B.$
See back effect is caused due to free electron density is different in different metals or free electron density in a metal depends on temperature.
