Solving an RLC Circuit: Seeking Help to Begin

[brad sue]

HI,
I don't really get this problem. Can I have some suggestion please?

The 3-mF capacitor of an RLC circuit is initially charged to 30 micronC.
The 1.5-mH inductor has a very small resistance.At particular instant, after 100 oscillations, the current through the inductor is zero while the capacitor is still charged at 5 micronC.
1- What is the resistance of the circuit?
2- what are the energies of the circuit before and after 100 oscillations?
Please Can I have some help so I can start?

thank you very much

It really would be best if you started it yourself. What do you have to work with? What do the relevant sections in your textbook say? Is this a series RLC circuit, or a parallel RLC circuit? Also, do you have an expression for any of the following quantities for your circuit?

* $q_C(t)$, the charge held by the capacitor
* $v_C(t)$, the voltage across the capacitor
* $i_L(t)$, the current through the inductor

Once you have one of the above you can use the given information to find the requested information.
