A single parallel plate capacitor is attached to a battery and charged. Then a dielectric is slid between the plates of the capacitor without disconnecting the capacitor from the battery. Describe what happens to the charge and potential difference of the capacitor. A single parallel plate capacitor is attached to a battery and charged, then the capacitor is disconnected from the battery. A dielectric is slid between the plates of the capacitor. Describe what happens to the charge and potential difference of the capacitor in this situation. A single parallel plate capacitor is attached to a battery and charged. Then two different dielectrics are slid between the plates of the capacitor without disconnecting the capacitor the battery. Describe what happens to the charge and potential difference of the capacitor two dielectrics.
