So, complete hypothetical on laws governing power transmission over a distance: Lets say I have a generator as a source of power - and attached to that is FIVE KILOMETERS worth of extension cords. :) In this situation, what laws of electricity do I need to look out for? Voltage drop over distance? Amp drop over distance? Gauge of wire? Risk of fire? There also might be something I need to know about the extension cord itself - the plug and the power cable components, whether a three prong grounded plug would be more advantageous as opposed to an ungrounded, two prong plug, etc. Please help me out :) thank you!
