4 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity …
Film capacitors: Characteristics and uses in power applications
In high volume, the absolute costs will be lower, but the ratios may remain similar. Film capacitors as snubbers Another high-value application for capacitors in power converters is in ''snubbing'', the deliberate slowing of switching waveforms to reduce EMI and semiconductor stress ( Figure 6 ).

A capacitor consists of two conductors separated by a non-conductive region. The non-conductive region can either be a vacuum or an electrical insulator material known as a dielectric. Examples of dielectric media are glass, air, paper, plastic, ceramic, and even a semiconductor depletion region chemically identical to the conductors. From Coulomb''s law a charge on one conductor wil…

For the parallel plate capacitor, electric field was constant between the plates all the time, therefore the energy density, energy per unit volume, is also constant. For the spherical as well as the cylindrical capacitors, the electric field is a function of the radial distance; therefore it will change point to point along the radial distance.
