Answer:
In this section, we will discuss the concept of electric flux, its calculation, and the analogy between the flux of an electric field and that of water. Let us imagine the flow of water with a velocity v in a pipe in a fixed direction, say to the right. If we take the cross-sectional plane of the pipe and consider a small unit area given by ds from that plane, the volumetric flow of the liquid crossing that plane normal to the flow can be given as vds. When the plane is not normal to the flow of the fluid but is inclined at an angle Ɵ, the total volume of liquid crossing the plane per unit time is given as vds.cosƟ. Here, dscosƟ is the projected area in the plane perpendicular to the flow of the liquid.
The electric field is analogous to the flow of liquid in the case shown above. The quantity we are going to deal with here is not an observable quantity as the liquid we considered above.
Electric Flux Formula
The total number of electric field lines passing a given area in a unit time is defined as the electric flux. Similar to the example above, if the plane is normal to the flow of the electric field,
