AC Circuits Solutions

Problem 1: Look at the (ideal, R = 0) LC circuit we discussed in Lec-
ture on 2022-04-07. Make time-aligned plots of the charge Q(t), current
I(t), energy in the capacitor Uc = (1/2)Q2/C, energy in the inductor
UL = (1/2) L 12, and total energy Uc + U, as a function of time over two
periods.
Be sure to label very clearly the minimum and maximum values of all five
curves (these will be expressions involving Qo, L,C), and be sure to label all
the time locations of any zero-crossings.
