 Homework Statement:

A 300V dc power sup ply is used to charge a 25μF capacitor. After the capacitor is fully charged, it is disconnected from the power supply and connected across a 10mH inductor (at t = 0).
(a) Assume that the resistance in the circuit is negligible. Apply Kirchhoff’s loop rule to to find the capacitor charge, q(t), and the current, i(t).
Find the frequency and period of oscillation of the circuit. Find the magnetic energy and elec tricenergyatt=0andt=1.2ms.
 Relevant Equations:
 How do I use Kirchoff's rule here?

Find the frequency and period of oscillation of the circuit. Find the magnetic energy and electric energy at t=0 and t=1.2ms.
Relevant Equations: How do I use Kirchoff's rule in this example?
I calculated natural angular frequency, got f=320 Hz and T =1/f =3.1 ms
I also know how to calculate magnetic and electric energy having I and q
I just need help with the Kirchoff's rule.
