Q

What would be the diameter of a conductor with a cross-sectional area of one circular mil?

🔍 Key Concepts

• Definition of a circular mil in electrical conductor sizing • Relationship between area of a circle and its diameter • How a circular mil compares to square inches or regular area units

💭 Think About

• First, recall or look up the formal definition: what exactly is "one circular mil" in terms of diameter? • Think about whether a circular mil is defined by a formula you must compute, or if it is defined directly by a specific diameter. • Compare the answer choices to what you would expect for a very, very small wire—are we talking thousandths of an inch or tenths of an inch?

✅ Before You Answer

• Verify the exact wording of the definition of a circular mil (it is a standard definition, not a derived one). • Make sure you distinguish between mils (thousandths of an inch) and inches themselves. • Check that your chosen answer matches the correct number of decimal places corresponding to one mil in inches.
