How do you find the area vector in electric flux?

How do you find area vector?

Hence, for a simple rectangular plate defined by two vectors →a and →b the vector area is described as:

  1. →A=→a×→b.
  2. →A=∫Sd→S.
  3. ∮Sd→S=→0.

How do you find the area of a vector in a magnetic field?

The orientation of the area vector can be found by applying a right-hand rule. Curl the fingers on your right hand in the direction of the current flow. Your thumb, when you stick it out, gives the direction of the area vector.

How do you solve electric flux?

Solution: electric flux is defined as the amount of electric field passing through a surface of area A with formula Φ e = E ⃗ ⋅ A ⃗ = E A cos ⁡ θ Phi_e=vec{E} cdot vec{A}=E,A,costheta Φe=E ⋅A =EAcosθ where dot ( ⋅) is the dot product between electric field and area vector and θ is the angle between E and the …

What do you mean by area vector?

: the vector of a plane surface whose magnitude is the area of the figure and whose direction is that of a perpendicular to the plane of the figure.

What is the unit of area vector?

Consider the surface S defined by the Ampèrian loop ∂S. Then, a vector normal to this surface and with magnitude equal to the area of the surface is →a. This is commonly referred to as the vector area of S. Then, the unit vector ˆa is a vector parallel to →a, but with unit length.
