Simplify the block diagram

Wire size and voltage drop The cross-sectional area of wire is measured in circular mils (CM). 1 mil = 1/1000 inch CM = squaring of mil Example 1: Find CM for a piece of wire has a diameter of .008 of an inch. .008 = 8/1000 = 8 mils CM = 8² = 64 Find CM for a piece of wire has a diameter of .008 of an inch. 5. Find Cm for a piece of wire has a diameter of .064 of an inch. 6. Find CM for a Wire has 24 strands of wire and each strand is .012 inches in diameter.
