AP Physics C: E&M
10.4 Dielectrics
10.3 Capacitors
Four identical parallel-plate capacitors, each with capacitance \(C_0\) and air between plates separated by distance \(d_0\), are initially connected to identical batteries that maintain a constant potential difference \(V_0\).
Each capacitor then undergoes a different sequence of modifications, as described in the table:
Which of the following correctly ranks the final electrostatic energy \(U\) stored in each capacitor from greatest to least?
Each capacitor then undergoes a different sequence of modifications, as described in the table:
| Capacitor | Modification Procedure |
|---|---|
| 1 | The battery is disconnected, and then the plate separation is increased to \(2d_0\). |
| 2 | A dielectric slab of constant \(\kappa = 3\) is fully inserted while connected to the battery, and then the battery is disconnected. |
| 3 | The battery is disconnected, and then a dielectric slab of constant \(\kappa = 3\) is fully inserted. |
| 4 | The plate separation is increased to \(2d_0\) while connected to the battery, and then the battery is disconnected. |
