Question

. A conductor with a diameter of 100 mils has an area of

a. 100 kcmil.
b. 0.00785 in2.
c. 100 in2.
d. 0.01 cmil.

Answer 1

In order to answer the question, you need to know the area of a circle.
Area = pi * r^2
Area = 3.14 * (100/2) ^ 2
Area = 3.14 * 50^2
Area = 7850 mils^2 = 0.00785 in^2
