Assertion (A): In n type semiconductor, number density of electrons is greater than the number density of holes but the crystal maintains an overall charge neutrality.
Reason (R): The charge of electrons donated by donor atoms is just equal and opposite to that of the ionised donor.
- Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
- Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
- Assertion (A) is true, but Reason (R) is false.
- Assertion (A) is false and Reason (R) is also false.
Answer
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
