Based on the thickness of the rubber insulation and outside diameter, the diameter of the copper conductor is 0.376 inch.
<h3>What is the copper wire's diameter?</h3>
The diameter of the copper wire can be found by the formula:
= Outer diameter - ( 2 x cotton insulation) - (2 x rubber insulation)
Solving gives:
= 500/ 1,000 - (2 x 12/ 1,000) - (2 x 50 / 1,000)
= 0.5 - (2 x 0.12) - (2 x 0.05)
= 0.376 inch
= 376 / 1,000 inch
