3. A 60-uF capacitor is charged by connecting it to a 12.0 V battery. The capacitor is then disconnected from the battery and connected across a 1.50-H inductor. a. What is the angular frequency of electrical oscillations and the period of these oscillations? b. What is the initial charge on the capacitor? c. How much energy is initially stored in the capacitor? d. What is the charge on the capacitor 0.0230 s after the connection to the inductor is made? Interpret the sign of your answer. e. At the time given in part (d), what is the current in the inductor? Interpret the sign of your answer. f. At the time given in part (d), determine the total energy in the circuit
