A circuit has a battery voltage of 12.0 V, a 5.60 pF capacitor and a 300 kOhm resistor.
(a.) what energy is stored in the fully charged capacitor?
(b.) If the capacitor has a plate separation of 1.50 mm and an area of 9.50 x 10^-4 m^2, what is the magnitude of the electric field between the plates?
