NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Steady current | (i) Random collisions of electrons |
| (b) Drift velocity | (ii) Flow of charges in circuits |
| (c) Electric field | (iii) Causes acceleration of electrons |
| (d) Charge flow | (iv) Related to time between collisions |
A
a-ii, b-iv, c-iii, d-i
B
a-ii, b-iii, c-i, d-iv
C
a-iv, b-ii, c-iii, d-i
D
a-ii, b-i, c-iv, d-iii
Correct Answer
Option A
Detailed Explanation
A steady current is characterized by a consistent flow of charges in circuits (a-ii). Drift velocity relates to the average speed of charge carriers, which is influenced by the average time between their collisions (b-iv). An electric field causes the acceleration of electrons (c-iii), and the charge flow itself is a result of these motion dynamics (d-i).
