Aircraft wire size is determined by using a(n)?

Ohmeter
Wire gauge
Dial caliper
Ruler

The correct answer is: Wire gauge

A Ohmeter is an instrument used to measure electrical resistance. While knowing the resistance of an aircraft wire can be helpful, it is not the determining factor for its size. C: Dial caliper is a measuring tool used to measure the thickness or diameter of an object. While this can be used to determine the thickness of an aircraft wire, it is not the industry standard for determining wire size. D: Ruler is a measuring tool that is not precise enough for determining the size of an aircraft wire. Wire gauge, on the other hand, is specifically designed for this purpose and is the most reliable method for determining the correct wire size.
