Electric Circuits
A parallel plate capacitor has two plates of area separated by a distance in air. the capacitor is connected to a 9-volt battery. You insert between the two plates a slab of plastic that has a dielectric constant k=6. What will happen to the capacitance of the capacitor and to the energy stored in the capacitor when you insert the dielectric?
