Resonance, Bandwidth & Q Factor

A series L-C-RL\text{-}C\text{-}R circuit is connected to a source of A.C. current. At resonance, the phase difference between the applied voltage and the current in the circuit, is

Show answer and solution

Answer: (b)

  1. At resonance XL=XCX_L = X_C, so tan⁡ϕ=0⇒ϕ=0\tan\phi = 0 \Rightarrow \phi = 0.
  2. So the answer is (b) zero.
