Electric flux of uniform electric field¶
Electric field at a point in space can be found by placing there a test charge and measuring the electrostatic force that is applied to it.
Notation:
\(\\left( \vec a, \vec b \\right)\) (
dot(a, b)) is the dot product between vectors \(\vec a\) and \(\vec b\).
Notes:
Vector area is a vector quantity whose magnitude denotes the area of the surface it represents and whose direction denotes the orientation of the surface.
Conditions:
The electric field is uniform. This might be achieved by choosing a small enough surface that the electric field would be constant throughout it.
