JEE Main 2023 — Alternating Current Question with Solution
JEE Main 2023 (01 Feb Shift 1)
Question
Match the List-I with List-II.
| List I | List II | ||
| A | AC generator | I | Presence of both L and C |
| B | Transformer | II | Electromagnetic Induction |
| C | Resonance phenomenon to occur | III | Quality factor |
| D | Sharpness of resonance | IV | Mutual Inductance |
Choose the correct answer from the options given below:

Show full solutionCorrect option: C
Step-by-step explanation
(A) An AC generator works on the electromagnetic induction principle. So,
(B) The transformer works on the principle of mutual induction. So,
(C) Resonance occurs when the value of inductive and capacitive reactance have equal magnitude but a phase difference of . So,
(D) The sharpness of resonance is defined using the quality factor which explains how fast energy decay in an oscillating system.
