Electric Fields and Capacitance | Capacitors | Electronics …
The greater the difference of electrons on opposing plates of a capacitor, the greater the field flux, and the greater the "charge" of energy the capacitor will store. Because capacitors store the potential energy of accumulated electrons in the form of an electric field, they behave quite differently than resistors (which simply dissipate energy in the …
Charged dielectric/conductor in capacitor
It is a standard problem to consider a dielectric or a conductor between the parallel plates of a capacitor. But what happens to capacity, voltage, charge, inserting between the plates of an ideal $begingroup$ Then it depends on whether the terminals are connected to the battery or not. ...
Confusion regarding effect of dielectrics on energy stored in a capacitor
This is because when you insert a dielectric there is an attracting force that pulls the dielectric between the capacitor plates and this takes energy from the $frac{1}{2}CV^2$ equation. If you removed the dielectric a mechanical force is required and this returns the energy to what it formerly was.
