NEET Physics Resistance & Resistivity Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Series combination of cells | (i) e eq = e 1 + e 2 |
| (b) Internal resistance of cells | (ii) r eq = r 1 + r 2 |
| (c) Parallel combination of cells | (iii) e eq = e 1 - e 2 |
| (d) Voltage across a single cell | (iv) V = e eq - I r eq |
a-i, b-ii, c-iii, d-iv
a-i, b-iii, c-ii, d-iv
a-ii, b-i, c-iv, d-iii
a-ii, b-iv, c-i, d-iii
Correct Answer
Detailed Explanation
In a series combination of cells, the equivalent emf is the sum of their individual emf's (e eq = e 1 + e 2) and the internal resistance is also additive (r eq = r 1 + r 2). This is directly derived from the relevant equations in the NCERT context.
