Four capacitors (W-Z) have the same charge Q on them (i.e., +Q on one plate, -Q on the other plate). In addition, the table below specifies the dimensions of each capacitor:
W: Area A, separation d
X: Area 2A, separation d/2
Y: Area A, separation d/2
Z: Area 2A, separation 2d
1. Rank the capacitors from greatest to least capacitance.
2. Rank the capacitors from greatest to least electric potential difference between the plates.
3. Rank the capacitors from greatest to least electric potential energy stored in them.
4. Now all four capacitors are connected to four identical batteries. How, if at all, does the ranking of U change (from the previous question)?
| They all will have the same U | The order of ranking reverses |
| Can't be determined. |
The order of ranking does not change |
5. All four are connected to identical resistors. Rank their discharge times from longest to shortest.
