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

  1. AA-IV, B-II, C-I, D-III
  2. BA-II, B-I, C-III, D-IV
  3. CA-II, B-IV, C-I, D-III
  4. 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, A → I I (B) The transformer works on the principle of mutual induction. So, B → I V (C) Resonance occurs when the value of inductive and capacitive reactance have equal magnitude but a phase difference of 180 ° . So, C → I (D) The sharpness of resonance is defined using the quality factor which explains how fast energy decay in an oscillating system. D → I I I
