Transferring power from 20 km away. The materials I can use in the wire are silver, copper, aluminum, or iron and I have wire available with AWG#s of 10, 20, 30, and 40. The device I will be powering will draw a constant current of 0.1 A. The maximum voltage drop I can tolerate (V = IR) across the wire is 100 V. Which combinations of wire (material and AWG #) will have a voltage loss of less than 100V? Explain.
