MCQ
Match List I with List $II$

Choose the correct answer from the options given below:

  • A
    $A-I, B-IV, C-III, D-II$
  • B
    $A-IV, B-I, C-III, D-II$
  • C
    $A-IV, B-I, C-II, D-III$
  • ✓
    $A-I, B-IV, C-II, D-III$
✓

Answer

Correct option: D.
$A-I, B-IV, C-II, D-III$
d
$A - V$ lags by $90^{\circ}$ from I hence option $(I)$ is correct.

$B - V$ lead by $90^{\circ}$ from $I$ hence option $(IV)$ is correct

$\mathrm{C}-\mathrm{In} \mathrm{LCR}$ resonance $\mathrm{X}_{\mathrm{L}}=\mathrm{X}_{\mathrm{C}}$. Hence circuit is purely resistive so option $(II)$ is correct $D$ - In LCR series $V$ is at some angle from $I$ hence $(III)$ is correct

Hence option $(4)$ is correct.
