An electric railway locomotive produces a peak mechanical output power of $4.0\,\text{MW}$. It receives electrical power at $25\,\text{kV}$ through overhead wires. The locomotive’s overall efficiency in changing electrical power into mechanical power is $80\%$. What current is drawn from the overhead wires when the locomotive is running at maximum power?
- A$130\,\text{A}$
- B$160\,\text{A}$
- C$200\,\text{A}$
- D$250\,\text{A}$
