1. The problem statement, all variables and given/known data find iC(t) in the circuit and plot its waveform for t>=0. 2. Relevant equations i(t)=i(infinity)+e^(-at)[D1cos(wdt)+D2sin(wdt) D1= i(0)-i(infinity) D2=i'(0)+a[i(0)-i(infinity)] aux.: w0=(LC)^(-1/2) wd=sqrt(W0^2 - a^2) s1= -a+sqrt(a^2 - w0^2) s2= -a-sqrt(a^2 - w0^2) 3. The attempt at a solution just a bit confused would this be a parallel RLC after all? doesn't seem like it, cause after switch moves it seems to be in series, except for current srouce. then I would calculate R(eq) by adding those two resistance? 0.1+0.52=0.62ohm?? i also get iL(0-)=iL(0)=4mA and iC(0)=0 because no current through open circuit?
