How do you find the cross sectional area of a stranded wire?
The cross-section A is calculated according to the formula “Diameter² x Pi / 4”. I test this measurement on a cable whose cross-section I know. I measure a diameter of 3.1 mm.
What is the diameter of 20 gauge stranded wire?
Stranded Wire: Black, 20 AWG, 40 Feet
| Wire gauge (AWG) | Strand count | Outer diameter (mm / in) |
|---|---|---|
| 26 | 7 | 1.3 / 0.051 |
| 24 | 11 | 1.4 / 0.055 |
| 22 | 17 | 1.6 / 0.063 |
| 20 | 26 | 1.8 / 0.071 |
What is the cross sectional area of a cable?
Then we define the cross sectional area simply as the square of the wire’s diameter in mils and call that our area in units of “circular mils.” This makes number handling ever so much easier.
When the cross sectional area of wire is bigger which is lower?
The American Wire Gauge system or AWG standardizes the cross sectional area of a wires by assigning them an AWG number. As seen in Figure 1, a lower numbered gauge wire has a larger diameter and thus is able to carry higher currents.
What is the formula for cross sectional area?
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.
Is cross sectional area the same as 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.
Is 6 gauge wire solid or stranded?
The choice between solid or stranded depends on the need for flexibility in handling and working with the wire. Smaller electrical wire sizes are generally made of solid conductors while wires larger than Number 6 AWG are generally stranded.
What is the formula of cross-sectional area?
Cross-sectional area is determined by squaring the radius and then multiplying by 3.14. For example, if a tree is measured as 10” DBH, the radius is 5”. Multiplying 5 by 5 equals 25, which when multiplied by 3.14 equals 78.5. Thus, the cross-sectional area of a 10” DBH tree is 78.5.
How do you convert diameter to cross-sectional area?
The cross-sectional area of the wire A is the area of a circle of radius r, or of diameter d = 2r: A=πr2=π(d2)2.
How is the cross sectional area of a wire determined?
This calculator determines the wire’s cross sectional area based on the number of strands and individual strand diameter. Please enter the number of strands. Then enter the strand diameter OR the CSA. A wire size chart can be found here.

What do you mean by cross sectional area?
The cross section or the cross sectional area is the area of such a cut. It need not necessarily have to be a circle. Commercially available wire (cable) size as cross sectional area:
