I recently picked up a study guide for my state exam. It has some basic practice questions on ohms law and voltage drop. It provides the answers but not how to get them. I'm trying to run the calculation and am getting different answers. Help?
Q1. How far from a 12 volt source can you install a #16AWG coated conductor, if the branch circuit load is 0.75 amp?
A1. 47.2 feet
Q2. What size copper conductor is required to a 1.5 amp load, 75 feet from the 24 volt supply?
A2. #14AWG
