Voltage Drop Across Transmission Lines

Click For Summary
SUMMARY

The discussion focuses on calculating the voltage drop across a pair of power transmission lines with a resistance of 0.850 Ω each, carrying a current of 779 A over a distance of 9.85 km. The input voltage is specified as 39.5 kV. The voltage at the receiving end can be determined by applying Ohm's Law and the formula for voltage drop, which is essential for understanding power transmission efficiency.

PREREQUISITES
  • Understanding of Ohm's Law
  • Knowledge of voltage drop calculations

Homework Statement


A pair of power transmission lines each have a 0.850 Ω resistance and carry 779 A over 9.85 km. If the rms input voltage is 39.5 kV, calculate the voltage at the other end.


Homework Equations





The Attempt at a Solution


 
Physics news on Phys.org
where is your own workings, relevant equations/concepts?
identify what is what first and foremost if you are stuck
 
Do you have the entire problem stated correctly? I think it might be 0.850 ohms/m instead.

Plus you need to put forth some effort first.
