A battery is connected to a capacitor in order to set up a potential difference

Question

A battery is connected to a capacitor in order to set up a potential difference across the plates. While the battery remains connected, a dielectric is inserted between the plates of the capacitor. Which of the following statements concerning the capacitor with the dielectric is false? (and why)?

A. The potential difference across the plates of the capacitor is the same as before

B. The amount of charge on the plates has increased

C. The capacitance of the capacitor has increased

D. The net electric field between the plates has increased

E. The capacitor stores more energy

Explanation / Answer

D. The net electric field between the plates has increased

since the battery voltage connected across the plates does not change as we insert the dielectric . hence the electric field between the plates remain constant too. hence the above statement is false.
