Hi All ,(adsbygoogle = window.adsbygoogle || []).push({});

I was thinking about the time domain unit step response of ideal series LC crcuit. If both cap and inductor are ideal and unchrged initially and I am looking at voltage accross capacitor.

Connecting a battery to LC circuit at t=t1 , would the circuit oscillate ?

I am not able to imagine this situation in terms of current and voltages of inductor /capacitor.I would be greatful if someone could intutively expain (without math and analogies) what exactly would happen.

My another question is, in case of underdamped response of RLC . I am again not able to think what causes the ringing behaviour with respect to inductor / capacitor current and voltage.
