... Since power lines have resistance, some portion of the electrical energy is lost as heat as the wires get hot. Since the length of the power lines increases the resistance, large amounts of heat can be produced. How can we reduce the amount of heat produced? ...

... No. One key assumption in the derivation of this fact was that all the charges were static. They settle into their equilibrium position (where they feel no force) after a very brief period of time and thus there are no electric fields. However for a closed circuit with an applied field along the len ...
