Parallel AC Circuits

An alternating voltage of frequency 'ω\omega' is induced in electric circuit consisting of an inductance 'LL' and capacitance 'CC', connected in parallel. Then across the inductance coil

Show answer and solution

Answer: (d)

  1. For L and C in parallel, the impedance is Z=ωL∣1−ω2LC∣Z = \frac{\omega L}{|1-\omega^2 LC|}.
  2. At ω2=1/LC\omega^2 = 1/LC, Z→∞Z \to \infty (parallel resonance) and the line current is minimum.
  3. The induced voltage across the coil is then maximum, so the answer is (d).
