Problem
A 1.0μF parallel-plate capacitor is charged to a potential difference of 120V and then disconnected from the battery, so the charge on the plates remains constant. A dielectric slab with dielectric constant κ=4.0 is completely inserted between the plates without changing their separation or area. Determine the new potential difference across the plates after the dielectric is inserted.
