The standard measuring unit of wire by its cross-sectional area, as used in American wire tables is measured how?
⢠American wire size units are based on cross-sectional area, not volume ⢠In U.S. electrical practice, the traditional unit for wire area uses the diameter in mils (thousandths of an inch) ⢠Think about how a round wireâs area is usually described: does it use square units, circular units, or cubic units?
⢠First, decide whether area should be measured in square units or cubic unitsâwhat does area represent? ⢠For a round wire, is it more natural to describe its size by a unit that relates directly to its diameter, or by standard metric area units? ⢠Look at the options that clearly relate to volume versus those that relate to area, then focus on the traditional American electrical terminology.
⢠Eliminate any options that refer to volume (cubic) rather than area ⢠Identify which option is a traditional U.S. electrical engineering term for wire cross-sectional area ⢠Confirm that the correct unit is based on mils (0.001 inch) and is used specifically for round conductors in American wire tables
