Energy density formula in electrostatics
WebDec 17, 2024 · $\begingroup$ Thank you. If my understanding is correct, electric energy density must depend on the field in the medium rather than the cause. So, I've some trouble understanding this statement - "Therefore, since we have the same electric field magnitude associated with more charges, we have a larger "field density", and hence a larger … WebEnergy Density Within Dielectric Medium. Consider a system of free charges embedded in a dielectric medium. The increase in the total energy when a small amount of free charge is added to the system is given by.
