7. You have a 1.0 F capacitor and a spool of wire with diameter of 0.25 mm and want to build a 1.0 Hz oscillator. You find a cardboard cylinder 4.0 cm in diameter and decide to use it for your inductor. The cardboard cylinder isn't long enough, so you end up with two layers of closely spaced turns. You charge the capacitor, and connect it in a circuit with the inductor and an ideal ammeter (no resistance). The maximum current that the ammeter registers is 6.5 A. a. How long did you inductor end up being? b. Find the maximum charge on the capacitor. c. What is the energy stored in the capacitor at an instant when the ammeter shows 4.0 A.
