Discharging a capacitor through an inductor creates oscillations. This is about as much as I understand about it. I'm having a hard time explaining my question so I attached a pic. My questions: 1. In circuit A, are there oscillations in the inductor as the battery charges the first capacitor? 2. In circuit B, does the pulsed dc signal allow for oscillations in the inductor? Does the frequency of the pulses effect the resonant frequency of the lc circuit?
