Reference no: EM13554212

An empty capacitor is connected to a 11.9-V battery and charged up. The capacitor is then disconnected from the battery, and a slab of dielectric material (κ = 2.2) is inserted between the plates. Find the magnitude of the amount by which the potential difference across the plates changes.
