Answer:
It is given that power = 5000 W for 120 V and resistance is [tex]1.24\Omega[/tex] per 1000 ft of wire. The wire is 750 ft away from 120 V source. We need find the voltage delivered to this load.
[tex]Power, P=Voltage(E)\times Current(I)[/tex]
[tex]\Rightarrow I=\frac{P}{E}=\frac{5000W}{120V}=41.67 A[/tex]
Resistance of 750 ft wire, =[tex]R=\frac{1.24\Omega}{1000 ft}\times750 ft=0.93\Omega[/tex]
Using Ohm's Law:
Voltage delivered to the load, [tex]V=IR[/tex]
[tex]\Rightarrow V=41.67A\times0.93\Omega=38.75 V[/tex]
