A parallel plate air capacitor, connected to a battery, has charge `Q_0`, potential difference between its plates `V_0`, electric field `E_0` and energy stored `U_0`. Now the intermediate space is completely filled with a dielectric, keeping the battery still connected. Then the quantities become Q, V, E and U, respectively. Which of the following statements are correct
`V gt V_0`.
