NEET Physics Resonance Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Resonance in a metal detector | (i) Sharp tuning of frequency |
| (b) Tuning a radio station | (ii) Both L and C must be present |
| (c) Current amplitude at resonance | (iii) Impedance changes with metal |
| (d) Requirement for resonance | (iv) Maximum current in AC circuit |
a-iii, b-i, c-iv, d-ii
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-iv, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
The metal detector operates on the principle of resonance, which results in a change in impedance when metal is present (a-iii). Tuning a radio involves adjusting the circuit to achieve maximum current at a specific frequency (b-i). The current amplitude at resonance is indeed maximum (c-iv), and both L and C must be present for resonance to occur (d-ii).
