Coated vs. Uncoated Conductor Properties
Working through the "Electrical Fundamentals" book I am working on a problem which states, "What is the voltage drop of two 12AWG conductors supplying a 16A load, located 100ft from the power supply?"
Referring to Table 8 "Conductor Properties" I see that 12 AWG can be Qty 1 or 7 so I'm going with 1, and Copper can be Uncoated 1.93Ohm/kFT or 2.01Ohm/kFT.
My question is, on the exam, if the question doesn't specify coated vs. uncoated, should I go with Coated? Coated fits the problem in the book with 2.01Ohm/kFT = .201Ohm/100FTx2 = .4Ohm resistance * 16A = 6.4V.
