The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object – such as a cylinder – is sliced perpendicular to some specified axis at a point. ... For example, the cross-section of a cylinder – when sliced parallel to its base – is a circle.
What is area of cross-section in A circuit?
Since the cross-sectional area of a circular cross-section is given by the expression PI•R 2 , wire A must have one-half the radius of wire B and therefore one-half the diameter. Put another way, the diameter of wire B is two times greater than the diameter of wire A.
How do you find the area of A cross-section?
Cross-Sectional Area of a Rectangular Solid
The volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h . Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.
What is difference between area and cross-sectional area?
Area is somewhat that is occupied by an object when it is resting on asurface i.e area is the space which isused by the object. Whereas cross-sectional area is an area which we obtain when the same object is cut into two pieces .
What is a cross section diagram?
A cross-section shows the shape of a feature (such as a mountain) viewed from the side , as if cut through with a knife. Cross-sections are constructed using the contour lines on a topographic map.
What is an area formula?
Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width . As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s 2 (square).
What is the meaning of cross section in electricity?
A cross section is the two-dimensional area you would get by cutting through the a conductor with a plane . For eg., a cylindrical conductor, if cut the normal way, has a circular cross section.
What is a cross section in math?
A cross-section is a plane section that is a section of a three-dimensional object that is parallel to one of its planes of symmetry or perpendicular to one of its lines of symmetry . Describe shapes formed by cross-sections (square, rectangle, triangle, etc).

What is the area of cross section of a prism?
Volume of a prism = Area of the Cross-Section x Length
The cross-section is the two dimensional shape repeated throughout the prism’s length. You simply work out the area of this cross-sectional shape (using your knowledge on area) and then multiply that area by the length (sometimes referred to as the depth).
Does cross-sectional area affect resistance?
Resistance is directly proportional to length. The cross section area A. Resistance is inversely proportional to cross section area .
How do you describe a cross section?
A cross section is the shape we get when cutting straight through an object . The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it.
What are the steps in drawing a cross section?
- Take a thin strip of paper and place it along the cross-section line. ...
- Take that strip of paper and put it on a fresh piece of paper. ...
- Draw dots corresponding to the elevations along the strip of paper representing the cross-section line.
- Draw a smooth line connecting the dots.
What is a cross section profile?
A graphic representation of the sections that are in a linear work , on cutting the axis of the aforementioned work with vertical planes perpendicular to it and defining the trace in elevation.
What is SI unit of area?
The SI unit of area is the square meter (m 2 ) , which is a derived unit.
