Question

When a dielectric is completely inserted between a capacitor’s plates, what does its dielectric constant represent?

Options

• The factor by which the capacitance decreases

• The factor by which the charge on an isolated capacitor decreases

• The factor by which the plate area decreases

• The factor by which the capacitance increases

Answer 1

The dielectric constant is also the factor by which capacitance increases when a dielectric is completely inserted. For a full slab, the new capacitance is \[C=KC_0\].
