Final answer:
Global standards for conductor stranding include maximum resistance and maximum cross-sectional area, which determine the capacity of the conductor to carry current and minimize power loss. The resistance is inversely proportional to the cross-sectional area, and a larger cross-sectional area allows for a higher current-carrying capacity.
Step-by-step explanation:
The global standards for conductor stranding include maximum resistance and maximum cross-sectional area. These standards are important in determining the capacity of the conductor to carry current and minimize power loss due to resistance. The maximum resistance ensures that the conductor has low electrical resistance, while the maximum cross-sectional area allows for a higher current-carrying capacity.
For example, if we compare two wires of the same material and length, but one has double the diameter of the other, the wire with the larger diameter will have lower resistance. This is because resistance is inversely proportional to the cross-sectional area of the conductor. So a larger cross-sectional area means a lower resistance.
Similarly, the maximum cross-sectional area also allows for a higher current-carrying capacity. A larger cross-sectional area provides more space for electrons to flow, resulting in less resistance and heat generation. This helps to ensure efficient and safe electrical conductivity.
