Answer to Question #275383 in Electrical Engineering for klemens

Question

What is the equivalent area in sq. inch for a conductor 336 400 circular mil?

Answer 1

As we know, 1 square inch is about 1.273·10⁶ circular mils, so, the area is

$$A_1=336/(1.273·10^6)=2.64·10^{-4}\text{ in}^2.\\ A_2=400/(1.273·10^6)=3.14·10^{-4}\text{ in}^2.$$
