Polarization (P) and maximum applied electric field (E max) are the most important parameters used to evaluate electrostatic energy storage performance for a capacitor. Polarization (P) is closely related to the dielectric displacement (D), D = ɛ 0 E + P, where ɛ 0 is the vacuum permittivity and E is applied electric field.

A capacitor attached to the flash gun charges up for a few seconds using energy from your camera''s batteries. (It takes time to charge a capacitor and that''s why you typically have to wait a little while.) Once the capacitor is fully charged, it can release all that energy in an instant through the xenon flash bulb.
