NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Maximum current from a cell | (i) e/r |
| (b) Internal resistance of cells | (ii) Prevents permanent damage |
| (c) Cells in series | (iii) Equivalent emf |
| (d) Cells in parallel | (iv) Replaced by single cell |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The maximum current from a cell occurs when the external resistance is zero, given by I max = e/r. The internal resistance of cells is generally kept low to prevent permanent damage, and multiple cells can be combined in series to calculate an equivalent emf, while cells in parallel can be replaced by a single equivalent cell.
