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). ...
Lecture Notes Chapter 2
In most applications the source charges are not discrete, but are distributed continuously over some region. The following three different distributions will be used in this course: 1. line charge λ: the charge per unit length. 2. surface charge σ: the charge per unit area. 3. ...
