Here is the question which I am struggling on, please help me!
Question: Power transmission lines often use a form of electric current called alternating current, but in many regions, such as the Province of Quebec, high-voltage direct-current lines are used instead. Direct current is the kind of electric current you are studying in this chapter. A certain direct-current power transmission line has a resistance of 0.255 W/km. 812 kV of potential drives the current from the generating station to a city located 125 km from the plant.
A- What is the power loss due to resistance in the line?
I need expert help to solve the above question.
