Q. In recent years it has been possible to buy a 1.0 capacitor. This is an enormously large amount of capacitance. Suppose you want to build a 3.6 oscillator with a 1.0 capacitor. You have a spool of 0.30--diameter wire and a 3.2--diameter plastic cylinder. How long must your inductor be if you wrap it with 2 layers of closely spaced turns?

Q. The capacitors are reconnected in series, and the combination is again connected to the battery. From the same choices, choose the one that is true.

All capacitors have the same charge, and the equivalent capacitance is greater than the capacitance of any of the capacitors in the group.

The potential difference across each capacitor is the same, and the equivalent capacitance is greater than any of the capacitors in the group.

The capacitor with the largest capacitance carries the smallest charge.

The capacitor with the smallest capacitance carries the largest charge.

The potential differences across the capacitors are the same only if the capacitances are the same.
