In recent years it has been possible to buy a 1.0 F
capacitor. This is an enormously large amount of
capacitance. Suppose you want to build a 1.1 Hz
oscillator with a 1.0 F capacitor. You have a spool of
0.35-mm-diameter wire and a 3.1-cm-diameter
plastic cylinder.

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.
In an L-C circuit, C= 3.21 μF and L = 88.0 mH . During the oscillations the maximum current in the inductor is 0.853 mA. What is the maximum charge on the capacitor? What is the magnitude of the charge on the capacitor at an instant when the current in the inductor has magnitude 0.497 mA?
