Show answer and solution

Answer: (a)

  1. Each element has the full source voltage e=e0sin⁡ωte = e_0\sin\omega t.
  2. Inductor: iL=1L∫e dt=−e0ωLcos⁡ωti_L = \frac{1}{L}\int e\,dt = -\frac{e_0}{\omega L}\cos\omega t
  3. Capacitor: iC=Cdedt=e0ωCcos⁡ωti_C = C\frac{de}{dt} = e_0\omega C\cos\omega t
  4. So the answer is (a).
