A given wire has a resistance of 3.90 Ω per 1000 ft. A 79-ft extension cord made of this wire is used simultaneously with an entertainment system that draws 7 A and a toaster that draws 15 A. (An extension cord has two wires in it.)
a) If the voltage at the wall socket is a constant 120 V, how much voltage is available at the tools?
b) How much power is lost in the extension cord?
