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)→II\left(A\right) \to II

(B) The transformer works on the principle of mutual induction. So, \left(B\right) \to IV</p><p>(C)Resonanceoccurswhenthevalueofinductiveandcapacitivereactancehaveequalmagnitudebutaphasedifferenceof</p><p>(C) Resonance occurs when the value of inductive and capacitive reactance have equal magnitude but a phase difference of180 °.So,(C)→I. So, \left(C\right) \to I

(D) The sharpness of resonance is defined using the quality factor which explains how fast energy decay in an oscillating system. (D)→III\left(D\right) \to III
