Wires aren't really ideal. The voltage drop across a current-carrying wire can be significant unless the resistance of the wire is quite low. Suppose a 100 ft extension cord is being used to provide power to an electric lawn mower. The cord carries a 10 Acurrent. The copper wire in a typical extension cord has a 1.3 mm diameter. Part A What is the voltage drop across a 100 ft length of wire at this current? Express your answer using...
