A parallel plate capacitor of capacitance C0 has plates of area A with separation d between them. When it is connected to a battery of voltage V0, it has charge of magnitude Q0 on its plates. While it is connected to the battery, the space between the plates is filled with a material of dielectric constant 3. After the dielectric is added, the magnitude of the charge on the plates and the new capacitance are
◦ Q0,
C0
◦ Q0,
C0
◦ Q0, C0
◦ 3Q0, C0
◦ 3Q0, 3C0
