Are there electric field lines in capacitors
As your capacitor discharges, the electric field intensity gets smaller and that energy has flowed into the resistor, but the energy that flows into the resistor in a small moment in time is energy from right nearby, and just before the resistor there is a high conductive material with very low electric fields, so not much electromagnetic ... - Download [PDF]

Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.

Drawings using lines to represent electric fields around charged objects are very useful in visualizing field strength and direction.Since the electric field has both magnitude and direction, it is a vector. Like all vectors, the electric field can be represented by an arrow that has length proportional to its magnitude and that points in the correct direction.

Electric field outside a capacitor
$begingroup$ The fields outside are not zero, but can be approximated as small for two reasons: (1) mechanical forces hold the two "charge sheets" (i.e., capacitor plates here) apart and maintain separation, and (2) there is an external source of work done on the capacitor by some power supply (e.g., a battery or AC motor). Remove (1) and the two "sheets" will begin to oscillate …
