Question

Calculate the voltage drop on a # 1/0 copper wire supplying a 125-amp, 240-volt load located 237' from the last overcurrent protective device?

Answer 1

Answer with explanation: We have to find the Voltage drop in a voltage that has the resistance of 1.02Ohms (1/10G), the formula used is:

`V=IR`

The voltage drop therefore is:

`\begin{gathered} V=(125A)\cdot(1.020\Omega)=127.5V \\ V=127.5\text{Volts} \end{gathered}`
