In recent years it has been possible to buy a 1.0 F capacitor. This is an enormously large amount of capacitance. Assume you want to build a 1.0 Hertz oscillator with a 1.0 F capacitor. You have a spool of 0.25 millimeter diameter wire and a 4.0 centimeter diameter plastic cylinder. Obtain how long must your inductor be if you wrap it with 2 layers of closely spaced turns?
