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:
Options
- AA-IV, B-II, C-I, D-III
- BA-II, B-I, C-III, D-IV
- CA-II, B-IV, C-I, D-III
- DA-IV, B-III, C-I, D-II
Correct answer
C. A-II, B-IV, C-I, D-III
Step-by-step solution
(A) An AC generator works on the electromagnetic induction principle. So,
(B) The transformer works on the principle of mutual induction. So, \left(B\right) \to IV180 °
(D) The sharpness of resonance is defined using the quality factor which explains how fast energy decay in an oscillating system.
