A parallel-plate capacitor has capacitance
4.00\mu F
. (a) How much energy is stored in the capacitor if it is connected to a
16.00-V
battery?
?
\mu J
(b) If the battery is disconnected and the distance between the charged plates doubled, what is the energy stored? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully.
\mu J
(c) The battery is subsequently reattached to the capacitor, but the plate separation remains as in part (b). How much energy is stored?
?
\mu J
