AnLC circuit The 38 pF capacitor is initially charged by the 8 V battery when Sis at position a. Then S is thrown to position b so that the capacitor is shorted across the 18 mH inductor.
1. What is the natural angular frequency of the circuit?
2. What is the maximum energy stored in the magnetic field of the inductor?
3. What is the maximum value for the oscillating current assuming no resistance in the circuit?
