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) Forward bias | (i) Threshold voltage ~0.7V |
| (b) Reverse bias | (ii) Controlled flow of electrons |
| (c) Vacuum tube | (iii) Reverse saturation current |
| (d) Diode current | (iv) Exponential increase after threshold |
A
a-i, b-iii, c-ii, d-iv
B
a-iv, b-ii, c-iii, d-i
C
a-iii, b-iv, c-i, d-ii
D
a-ii, b-i, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
In forward bias (a), the diode current increases significantly after reaching the threshold voltage of ~0.7V (i). In reverse bias (b), the current is known as reverse saturation current (iii). Vacuum tubes (c) are devices that allow a controlled flow of electrons (ii). The diode current (d) indeed exhibits an exponential increase after the threshold is crossed (iv).
