Solving LC circuit with energy conservation
Reply to thread

[QUOTE="DaveE, post: 6810947, member: 644223"] He must be assuming that the capacitor breakdown is much quicker than the response time of the LC resonator, so the inductor current doesn't change. However, the phrase "the amplitude of charge oscillations after the breakdown" is confusing. The only oscillations in this circuit must include the inductor, RC circuits don't oscillate. To find the peak capacitor energy ("amplitude of charge oscillations"), you would have to include the inductor energy. Alternatively, you could just describe the charge on the capacitors immediately after the fast breakdown event, which should be zero for one and unchanged for the other (as I interpret his problem). Yet another example of a poorly worded problem. I guess he's describing the nature of the initial transient and asking for the LC response following that event? [/QUOTE]
