Finding Max and Min in Oscillating LRC Circuit

Click For Summary
SUMMARY

The discussion focuses on calculating key parameters in an oscillating LRC circuit with inductance (L) of 3.00 mg and capacitance (C) of 2.70 x 10^-6 F. The maximum charge (Q_m) on the capacitor is determined using the formula Q_m = C * U_m, where U_m represents the maximum voltage. Additionally, participants discuss identifying the earliest time when energy stored in the capacitor is maximized and the greatest rate of current flow. The problem-solving process is simplified through collaborative assistance from forum members.

In an oscillating LC circuit L = 3.00 mg and C = 2.70 * 10^-6. At t=0 the charge on the capacitor is zero and the current is 2.00 Am.

What is the maximum charge that will appear on the capacitor?
The earliest time where energy stored in the capacitor is the greatest?
What is the greatest rate?

Our teacher just barely touched upon finding the max and the mins in the oscillating of a LRC circuit. I haven't a clue even where to start. Could i get some help setting up the problem?
