A copper conductor that is 150 meters in length has a resistance of .14 ohms. If the current flow through the conductor is 50 amperes, the voltage drop along the conductor is?

Welcome to the forum.

Do you have access to the formula for voltage drop?

Use Ohm's law.

If you do not know about Ohm's law, then do a Google search for information. and report back with your solution.

In an actual circuit you will likely have two wires of equal diameter, length, and material. What is the voltage drop between the source voltage, and the load?

Note that the fact the wire is n metres in length in this problem is not a relevant factor, however its resistance most definitely is.

Correct, the length does not matter, only the resistance.

It could be 1500 meters with .14 ohms and the voltage drop would be the same.

VD = I*R*cos(a) + I*X*sin(a)
where cos(a) = power factor
Note that you need both resistance R and reactance X. Also, if this is single-phase, the current flows both ways, so R and X have to include the return conductor.
