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 …
