  1. The resonant frequency of the given series is—


    1. 1
      		Hz
      2 π 3
    2. 1
      		Hz
      4 π 3
    3. 1
      		Hz
      4 π 2
    4. 1
      		Hz
      2 π 2
Correct Option: D

f1 =
1
2 π√Leq C

here L eq = L1 + L2 – 2M
= 2 + 2 – 2 × 1 = 2
so C = 1 F
fr =
1
=
1
2 π√2 × 12 π√2
