    Controled electric energy extraction from clouds

    When someone mentions exploatation of an electric (electrostatic) energy from clouds one would instantaneously imagine a gigantic capacitor (or some other sort of an "acumulator" for such energy) and a loud BANG(!) when thunder strikes it and polirizes it all at once; but isn't it possible to...

    Supposition about heat energy transferring to electric energy

    Supposition about heat energy transferring to electric energy The supposition is based on static electric balance system and thermodynamics system . We suppose that a container( electron charge is not adsorbed on wall ) have tip electrode D(-100 V) ,and there is a metallic barrel(-101v) on...

    How Do Capacitors and Inductors Store Electric and Magnetic Energy?

    hi i am not exactly able to understand in which form or rather how electric and magnetic energy get stored in capacitor and inductor respectively... :shy:

    How to Calculate Electric Potential and Work for Multiple Charges?

    The way to solve this, i tried is by saying F = k(q1)(q2) / r^2. So, the force between the two charges is (9x10^9)(2.6x10^-8)(5.5x10^-8) / (1.4^2). Although, from there I'm not sure where to go because that just solves for the force inbetween the two charges and not the EPE or even more...

    Electric Energy: Experiment & Negative Potential

    1)two different formulas for electric field is a)U=(1/2)Q1V1+(1/2)Q2V2+... b)U=\int \frac{1}{2}\epsilon.E^2dv Using these how could we perform an experiment to test where the energy located? 2)Since the electric energy density is never negative, how can the mutual electric potential of...
