For a stranded cable:
Use a micrometre or vernier gauge to measure 1 strand; this gives you the diameter of the strand.
Halve this figure for the radius, square the number and multiply by pi.
(pi r squared is the area of a circle).
Finally multiply the result by the number of strands which then gives you the true csa of the stranded cable.

What wire has the greatest cross-sectional area?
The wire with the greatest cross-sectional area is typically a thick copper wire, such as that used in electrical applications, measured in American Wire Gauge (AWG). For example, a 0000 AWG (4/0) wire has a cross-sectional area of approximately 53.5 mm². In general, as the AWG number decreases, the wire diameter and cross-sectional area increase. Thus, the thickest wire in standard gauge systems will have the greatest cross-sectional area.
What happens to the cross-sectional area of metal wire if you double the diameter?
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
How do you work out the cross-sectional area of a wire?
Imagine the wire is straight, now cut through at right angle to the centre line, the exposed surface is the cross sectional area, on a round wire it = pi * radius2 (area of a circle)
How does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.
What happens to its cross-sectional area of the metal wire if you double the radius if you double its diameter?
If you double the diameter of a metal wire, you effectively double its radius as well. The cross-sectional area of a circular wire is given by the formula (A = \pi r^2). Therefore, if the radius is doubled, the new area becomes (A' = \pi (2r)^2 = 4\pi r^2), which means the cross-sectional area quadruples. Thus, when the diameter is doubled, the cross-sectional area increases by a factor of four.
Is the resistance of the wire directly or inversely proportional to the cross-sectional area of the wire?
The resistance of a wire is inversely proportional to the cross-sectional area of the wire. This means that as the cross-sectional area of the wire increases, the resistance decreases, and vice versa.

What is the cross sectional area of a wire?
If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.
What happens to the cross-sectional area of metal wire if you double the diameter?
If the diameter doubles (x2), the cross-sectional area quadruples (x4).

How do you find percentage reduction in wire drawing?
To find the percentage reduction in wire drawing, first calculate the reduction in cross-sectional area using the formula: ( \text{Reduction} = \frac{A_0 - A_f}{A_0} \times 100 ), where ( A_0 ) is the original cross-sectional area and ( A_f ) is the final cross-sectional area after drawing. Subtract the final area from the original area, divide by the original area, and then multiply by 100 to express it as a percentage. This gives the percentage reduction in the wire's cross-sectional area due to the drawing process.
What type of wire increases when it is made thinner?
Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!
Does the resistance of a wire depend on the cross section area of the wire?
No, the resistance of a wire primarily depends on its length, resistivity, and temperature. The cross-sectional area of the wire influences the wire's resistance indirectly by affecting the wire's overall resistance. A larger cross-sectional area generally results in lower resistance due to increased conducting area for current flow.
What happens to its cross-sectional area of the metal wire if you double the radius if you double its diameter?
If you double the diameter of a metal wire, you effectively double its radius as well. The cross-sectional area of a circular wire is given by the formula (A = \pi r^2).

What is cross-sectional area of a wire if its outside diameter is 0.0625 inch?

What happens to its cross-sectional area of the metal wire if you double the radius?
It quadruples.
