Homework Statement
Suppose you want to run some apparatus that is 75m from an electric outlet. Each of the wires connecting your apparatus to the 100V source has a resistance per unit length of 0.0055 ohms/m. If your apparatus draws 2.5 Amps, what will be the voltage drop across the connecting wires and what voltage will be applied to your apparatus?
Homework Equations
V=IR
The Attempt at a Solution
100=R x 2.5
So R= 40 Ohms
But don't know where to go from here!
