Picture: A battery like this stores electrical potential energy in a chemical form. When the battery is flat, it means you've used up all the stored energy inside by converting it into other forms.Electric circuitsFor an electric current to happen, there must be a circuit. A circuit is a...
The electric field near the surface (outside the conductor) is consideredlike(not the same) that of aninfinite plane. Butdifferent, in that the other half is theinside, whereE is 0. On theoutside, it'sE = \frac{\sigma}{\epsilon_0},twice the magnitudeof an infinite plane. (Why you...
Metal hydrides are not suitable for large-scale hydrogen storage, due to high material costs, but have potential in next generation “hybrid” buffer stores, enabling 6 times or greater improved hydrogen density compared to compressed gas alone. Underwater hydrogen storage, either in fixed or flexi...
