Question

The scalar product of electric field intensity and area vector through which the line of force emerges is ______.

Options

• electric potential

• electric current

• electric charge density

• electric flux

Answer 1

The scalar product of electric field intensity and area vector through which the line of force emerges is electric flux.

Explanation:

Electric flux is defined as the dot product of electric field intensity \[\vec E\] and area vector \[\vec A\], i.e., ϕ = \[\vec E\] . \[\vec A\] = E A cos⁡θ, giving a scalar value representing field lines passing through a surface.
