Two Capacitors
Capacitors A and B are charged by connecting them to identical batteries. Capacitor A has higher capacitance, even though the distance between the plates is the same for both capacitors. Which of the following statements is correct?
A) The capacitors have the same potential difference, but A has more charge stored and larger electric field between its plates.
B) The capacitors have the same potential difference and electric field, but A has more charge stored.
C) The capacitors have the same potential difference and electric field, but A has less charge stored .
D) Capacitor A has higher potential difference , more charge stored, and larger electric field.

Electric field E=V/d is the same for both capacitors, as well as the potential difference between the plates V. Since stored charge, being the product of capacitance and P.D., and A has more capacitance, more charge will be stored in it.
