Having trouble with this one: A capacitor having a capacitance of 10uF is charged by 100v battery. A.)Calculate the charge on the capacitor? B.)calculate the energy stored in the capacitor? C.) the terminals of the capacitor is now disconnected from the batery and the capacitor is now connected across a 20uF capacitor. Calculate the charge on each capacitor and the voltage across each?

  • physics -

    a,b are standard formulas.

    c. 2/3 of q goes to the new capacitor.

    then, each voltage can be found C=q/V or V=q/C
