Electric Flux
An electric charge specified as an only electron in space.It
has an electric field surrounding it. In pictorial pattern, this electric field
is shown as a dot, the direction indicating the lines of density. These are
called Guass lines. Electric Flux Density is the amount of flux, the number of
"lines," passing in a specific direction.
SI Unit
Electrical flux has SI units of volt meters (V/m), or,
equivalently, newton meters squared per coulomb (N m2 C−1). Thus,
the SI base units of electric flux are kg·m3·s−3·A−1.
Its dimensional formula is [L3MT−3I−1].
Explanation
Its Units are Gauss/square meter. If the electric field is
uniform, the electric flux passing through a surface of vector area S is
Here S is the electric field, E is its magnitude, S is the
area of surface and θ is the angle between electric field lines.
If the electric field is non-uniform then the electric flux
dΦE by area is given as
The electric flux over a surface S is given below
Here E is the electric field and dS is a diffference area on
the surface S.
According to Guass Surface
According to Guass Surface electric flux is given below
Here
E is the electric field,
E is the electric field,
S is any closed surface,
Q is the total electric charge inside the surface S,
ε0 is the electric constant
The equation is also known as the Guass Law for electric
field.
