Call your doctor at once if you have a serious side effect such as: 1  feeling short of breath, even with mild exertion; 2  swelling of your ankles or feet; 3  slow or uneven heartbeats; or. 4  numbness or cold feeling in your hands and feet.
For the most part, I understand the derivation; however, at the end of the derivation, the author adds one little condition: Where is the energy in a parallel plate capacitor actually stored? Well, if we think about it, the only place it could be stored is in the electric field generated between the plates..
A capacitor can be said to store energy. But no, a capacitor does not store electric charge. This is a very common misconception, especially among school level students. When charge enters into one terminal of a capacitor, an equal amount of charge leaves the other end. The total charge in a capacitor is always zero and in equilibrium with its surroundings.
