The capacitance of an empty capacitor is 1.2 mF. The capacitor is connected to a 12-V battery and charged up. With the capacitor connected to the battery, a slab of dielectric material is inserted between the plates. As a result, 2.6 × 10-5 C of additional charge flows from one plate, through the battery, and onto the other plate. What is the dielectric constant of the material? |
