The energy stored in a capacitor is nothing but the electric potential energy and is related to the voltage and charge on the capacitor. If the capacitance of a conductor is C, then it is initially uncharged and it acquires a potential difference V when connected to a battery.
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 already on the capacitor.
In this exercise, the capacitor is introduced in terms of its ability to store charge, and analyzed in terms of the relationship between charge and potential difference. The student also examines simple series and parallel …
Unfortunately, this process generates loose oxygen: 2(MnO 2) + (energy) --> Mn 2 O 3 + O. The difference between a successful self-healing event and a pyrotechnic failure is whether or not this oxygen finds tantalum metal at a high-enough temperature to auto-ignite.
