What is infinite wire?
14 2. infinite means no end on both sides semi infinite means which is fixed at one point and other point is not fixed eg line infinite and ray semi infinite.
What is an infinite sheet of charge?
For an infinite sheet of charge, the electric field will be perpendicular to the surface. Therefore only the ends of a cylindrical Gaussian surface will contribute to the electric flux . The resulting field is half that of a conductor at equilibrium with this surface charge density.
Why the electric field produced by an infinitely large plane is constant everywhere?
The enclosed charge is the same regardless of the length of the cylinder, so the flux through the ends must be also. Therefore the electric field is the same at any distance from the sheet.
How can you decide if a wire is infinite?
How can you decide if a wire is infinite? , the wire can be considered infinite. This judgment is based also on the precision you need in the result. Identical currents are carried in two circular loops; however, one loop has twice the diameter as the other loop.
What is a semi infinite wire?
semi infinite means it is fixed at one end and infinite at other like length is from 0 to infinity.
What is the surface charge density of the infinite plane?
An infinite plane of surface charge density σ = 4.5 nC/m2 n C / m 2 lies in the x = 0.00 m plane, and a second infinite plane of surface charge density σ = – 4.50 nC/m2 n C / m 2 lies in the x = 0.0200 in plane.
Why we are considering sheet as an infinite sheet of charge?
The surface charge density, the charge per unit area, is always σ even as we let the area of the sheet become very large — so large we don’t know the actual total area or charge so we model them by an infinite sheet.
On which of the following factors does the electric field due to an infinitely long wire does not depend?
Finally, since the wire is infinite, electric field does not depend on the position of P along the length of the wire. In short, the electric field is everywhere radial in the plane cutting the wire normally, and its magnitude depends only on the radial distance r.
What is the limitation of Ampere’s circuital law?
The main limitation of Ampere’s circuital law is that its only applicable in Magnetostatics or its only valid for the steady current.
What is the field of an infinite straight wire?
In the limit , on the other hand, we get the field of an infinite straight wire, which is a straight wire whose length is much, much greater than either of its other dimensions, and also much, much greater than the distance at which the field is to be calculated:
What is the difference between an infinite line and an infinite plane?
Well, the explanation really is held in Gauss’s Law. That shows that the field of an infinite line is distance dependent, while an infinite plane is not. But I expect you’re looking for a more intuitive answer. So I’ll give my best shot at one.
Why is the electric field of an infinite plane constant?
Having an infinite plane counteracts this diverging effect as adjacent lines keep the field directed perpendicular to the plane at a constant distance apart. You have the correct understanding of why the electric field is constant for any distance from the plane.
What does an infinite line of electric field look like?
With an infinite line, if you look at the infinite line from the top, it looks like a point charge, and point charges do not have constant electric fields.
