Electromagnetic Field Theory
The electrical field strength at a distance point A due to a point charge +q, located at the origin, is 100 µl v/m. If the point charge is now enclosed by a perfectly conducting metal sheet sphere whose centre is at origin, A, outside the sphere, becomes
For a uniform long charged line with l1 c/m the electric field intensity E is given as E = ρL/(π ε0.r).
An electric flux line is an imaginary path or a line drawn in such a way, that its direction at any point is the direction of electric field at that point.
Gauss’s law states that total electric flux through any surface is equal to the total charge enclosed by surface.
