A 3730.-nF parallel plate capacitor is connected to a 21.4-V battery and charged.
a) What is the charge Q on the positive plate of the capacitor?
b) What is the electric potential energy stored in the capacitor?
The 3730.-nF capacitor is then disconnected from the 21.4-V battery and used to charge three uncharged capacitors, a 150.-nF capacitor, a 235.-nF capacitor, and a 345.-nF capacitor, connected in series.
c) After charging, what is the potential difference across each of the four capacitors?
d) How much of the electrical energy stored in the 3730.-nF capacitor was transferred to the other three capacitors?
