On the nature of electric charge and static electric field

First, it is shown that in the capacitor, which is included in the DC circuit, there is there is a flow of electromagnetic energy, which continues to circulate even after disconnecting from the DC voltage source, and even when the metal plates are removed. Taking this fact into account, further, by analogy with the wave-AND-particle (WAP), the field-AND-particle (FAP) is described, which can be an electric charge or a holder of a static field.
