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..
Photo: Inside, an electrolytic capacitor is a bit like a Swiss roll. The plates are two very thin sheets of metal; the dielectric an oily plastic film in between them. The whole thing is wrapped up into a compact cylinder and coated in a protective metal case.WARNING: It can be dangerous to open up capacitors.nd this, if you've not guessed by now, is the energy that a capacitor stores. Its two plates hold opposite charges and the separation between them creates an electric field. That's why a capacitor stores energy.
