A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H .
(D)What is the charge on the capacitor 0.0235 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) Atthe time given in part (d), how much electrical energy is stored in the capacitor and how much is stored in the inductor?
