The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...

If we turn off the 25 Volt source, and then carefully connect a 10,000 Ohm resistor across the terminals of the capacitor, then we can calculate whether or not we will blow up the resistor and how long it will take to empty the capacitor. Current (through Resistor) = V / R = 25 Volts / 10k Ohm = 0.0025 Amps.
