Gauss’ Theorem

By /

Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Gauss’ Theorem: This theorem gives a relationship between the total flux passing through any closed surface and the net charge enclosed within the surface. ”Gauss’ theorem state that the total flux through any closed surface is 1/ε₀ times the net charge enclosed by the closed surface”. Mathematically, it …

Electric Flux

By /

Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Electric Flux: Electric flux linked with any surface is defined as the total number of electric field lines that normally passes through that surface. It is represented by ØE. Electric flux depends upon three factors. (I)   Area(A) (II)  Strength of electric field. (III)  Angle between area vector and …

Area Vector

By /

Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Area Vector: The vector associated with every area element of a closed surface is taken to be in the direction of the outward normal. Thus the area element vector ∆S at a point on a closed surface is equal to ∆Sn∧, where ∆S is magnitude of area …
