Energy loss
Part of the electrical energy generated by the generator turns into heat and is wasted uselessly in the line, causing heating of the conductor. As a result, the energy received by the receiver is always less than the energy given by the generator. In the same way, the power expended in the receiver is always less than the power developed by the generator.
Power losses in a line can be calculated knowing the current strength and line resistance: Ploss = I2Rl
To characterize the efficiency of energy transmission, the line efficiency is determined, which is understood as the ratio of the power received by the receiver to the power developed by the generator.
