NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) P-type semiconductor | (i) Excess electrons |
| (b) N-type semiconductor | (ii) Acceptors |
| (c) Depletion layer | (iii) Electron-hole pairs |
| (d) Forward bias | (iv) Barrier reduction |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iv, c-i, d-iii
D
a-iv, b-ii, c-iii, d-i
Correct Answer
Option A
Detailed Explanation
In a P-type semiconductor, acceptor impurities create holes, while in an N-type semiconductor, excess electrons are provided by donor impurities. The depletion layer forms at the p-n junction and under forward bias, the potential barrier is reduced, allowing current to flow.
