Created by StemPy LabIn an air capacitor with a gap , a sheet of dielectric constant and thickness is slipped in, lying flat between the plates. By what factor does the capacitance grow?
← All Quizzes
← A dielectric slab of constant 3.5 is placed in a field at right angles to its faces. What is the ratio of the bound charge on each unit of area of a face to the free charge on each unit of area of the plates that make the field?A capacitor is filled with oil of dielectric constant 2.6 and charged to 45 V. The battery is removed, and the oil is drained away. What is the voltage across the plates now? →
