    A charged 30 μF capacitor is connected to a 27 mH inductor. What is the angular frequency of free oscillations of the circuit?
    Ans : Capacitance, C = 30μF = 30×10-6F

    Inductance, L = 27 mH = 27 × 10-3 H

    Angular frequency is given as:



    Hence, the angular frequency of free oscillations of the circuit is 1.11 × 103 rad/s.
