Medium MCQ +4 / -1 PYQ · JEE Mains 2021

Match List - I with List - II

List - I List - II
(a) $\omega L > {1 \over {\omega C}}$ (i) Current is in phase with emf
(b) $\omega L = {1 \over {\omega C}}$ (ii) Current lags behind the applied emf
(c) $\omega L < {1 \over {\omega C}}$ (iii) Maximum current occurs
(d) Resonant frequency (iv) Current leads the emf


Choose the correct answer from the options given below

  1. A a(ii), b(i), c(iv), d(iii) Correct answer
  2. B a(ii), b(i), c(iii), d(iv)
  3. C a(iii), b(i), c(iv), d(ii)
  4. D a(iv), b(iii), c(ii), d(i)

Solution

$\omega L = {1 \over {\omega C}},{X_L} = {X_C}$<br><br>So current in phase with EMF<br><br>At resonance, current have maximum value.
