Question

What is positive flux?

Answer 1

Hint:In order to answer this question, it is crucial to understand what the definition of flux is before moving on to the issue. Flux can be classified as positive flux and negative flux.

Complete step by step solution:
Flux:Electric flux is a characteristic of an electric field that can be conceptualised as the quantity of electric lines of force that cross a specific region. When the flux exits the closed surface, it is considered to be positive. The surface area, magnetic field strength, and angle between the surface and the field all affect flux.

The net, or total, electric flux is zero because the magnitudes of the positive and negative fluxes are exactly equal. The total flux through a closed surface that contains a net charge is proportional to the enclosed charge, positive if the enclosed charge is positive and negative if it is negative. Negative electric flux occurs when lines of force are entering a surface.

Additional Information: The orientation of a closed surface, or a surface without any holes, is typically specified such that flux travelling from inside to outside counts as positive, outward flux and flux flowing from outside to inside counts as negative, inward flux.

Note: Electric flux is said to be positive, if flux lines are flowing outwards that is if \[\theta < {90^ \circ }\] is said to be negative, if flux lines are flowing inwards that is if \[\theta > {90^ \circ }\]. Electric field lines are considered to originate on positive electric charges and terminate on negative charges.
