Resonance, Bandwidth & Q Factor

In LCR series resonant circuit, at resonance, voltage across 'L' and 'C' will cancel each other because they are

Show answer and solution

Answer: (d)

  1. VLV_L leads current by 90∘90^\circ; VCV_C lags current by 90∘90^\circ.
  2. So VLV_L and VCV_C are 180∘180^\circ out of phase; at resonance they are equal in size and cancel.
  3. So the answer is (d) 180∘180^\circ out of phase.
