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 is cross-sectional area of a wire if its outside diameter is 0.0625 inch?
0.0031
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 does the cross sectional area of wire affect resistance?
Other things being equal, more cross-sectional area will cause less resistance.
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 is cross-sectional area of a wire if its outside diameter is 0.0625 inch?
0.0031
What happens to its cross-sectional area of the metal wire if you double the radius?
It quadruples.
Would have the same resistance as a copper wire that is 4 m long and has a cross-sectional area of 0.066 cm2?
A wire with the same resistance as the given copper wire would have the same resistivity as copper. The resistance of a wire is dependent on its resistivity, length, and cross-sectional area. To calculate the resistance of a wire, use the formula R = (resistivity * length) / area; however, without the specific resistivity value, an exact value cannot be provided.
Do bend in the wire effect the electric resistance?
Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.
