What is Stokes theorem in electromagnetic theory?
Stokes’ Theorem Formula The Stoke’s theorem states that “the surface integral of the curl of a function over a surface bounded by a closed surface is equal to the line integral of the particular vector function around that surface.”
What is the formula of Stokes theorem?
By Stokes’ theorem, ∬S1curl⇀F⋅d⇀S=∫C⇀F⋅d⇀r=∬S2curl⇀F⋅d⇀S.
What are the conditions for Stokes theorem?
Stokes’ Theorem is about tiny spirals of circulation that occurs within a vector field (F). The vector field is on a surface (S) that is piecewise-smooth. Additionally, the surface is bounded by a curve (C). The curve must be simple, closed, and also piecewise-smooth.
Who made Stokes theorem?
It is named after Sir George Gabriel Stokes (1819–1903), although the first known statement of the theorem is by William Thomson (Lord Kelvin) and appears in a letter of his to Stokes in July 1850. The theorem acquired its name from Stokes’s habit of including it in the Cambridge prize examinations.
What is Stokes theorem and divergence theorem?
Long story short, Stokes’ Theorem evaluates the flux going through a single surface, while the Divergence Theorem evaluates the flux going in and out of a solid through its surface(s). Think of Stokes’ Theorem as “air passing through your window”, and of the Divergence Theorem as “air going in and out of your room”.
Who invented Stokes theorem?
How do you prove Stokes law?
He found what has become known as Stokes’ Law: the drag force F on a sphere of radius a moving through a fluid of viscosity η at speed v is given by: F=6πaηv. Note that this drag force is directly proportional to the radius.
Which of the following operation is used in Stokes theorem?
Explanation: ∫A. dl = ∫∫ Curl (A). ds is the expression for Stoke’s theorem. It is clear that the theorem uses curl operation.
How was Stokes theorem invented?
From the scientific contributions of George Green, William Thompson, and George Stokes, Stokes’ Theorem was developed at Cambridge University in the late 1800s. It is based heavily on Green’s Theorem which relates a line integral around a closed path to a plane region bound by this path.
Who created Stokes theorem?
What is the difference between Gauss theorem and Stokes theorem?
Comparison between Stokes’s Theorem and Gauss’s Theorem : Both theorems can be used to evaluate certain surface integrals, but there are some significant differences: Gauss’s Theorem applies only to surface integrals over closed surfaces; Stokes’s Theorem applies to any surface integrals satisfying the above basic …
What are the limitations of stokes law?
1. Negative density difference in Stoke’s equation. Stokes’ equation is invalid if the density difference in the equation is negative that is when the particles are lighter than the dispersion medium. This results in floatation or creaming most commonly seen in emulsion systems.
Which of the following represent statement of Stokes theorem?
Stoke’s theorem statement is “the surface integral of the curl of a function over the surface bounded by a closed surface will be equal to the line integral of the particular vector function around it.” Stokes theorem gives a relation between line integrals and surface integrals.
Which of the following is true about Stokes theorem?
The Stoke’s theorem can be used to find which of the following? Explanation: It states that the line integral of a function gives the surface area of the function enclosed by the given region. This is computed using the double integral of the curl of the function.
Who proposed Stokes theorem?
What is the relationship of Gauss theorem and Stokes Theorem?
It relates the flux of a vector field through the closed surface to the divergence of the field in the volume enclosed. The Gauss divergence theorem states that the vector’s outward flux through a closed surface is equal to the volume integral of the divergence over the area within the surface.

How do you use the divergence theorem in Maxwell’s equation?
Using Divergence Theorem (ii) Comparing the two volume integrals in (i) and (ii) This is the first Maxwell’s equation. It states that the volume charge density is the same as the divergence of the electric flux density.
