I am wondering why in a small unit of area for a surface S in an electric field. The flux of the small area is the dot product of E and s where s is the normal vector and makes an angle theta to the field. Why do we use the dot product of E and s, why does it give us the flux of the small area?(adsbygoogle = window.adsbygoogle || []).push({});
