AC is generally more efficient than DC for long-distance electrical power transmission because it can be easily converted to higher voltages, reducing energy losses during transmission.
Electrical efficiency is calculated by dividing the useful output power (in watts) by the input power (in watts) and multiplying by 100 to get a percentage. The formula is: Efficiency = (Useful output power / Input power) * 100. The higher the percentage of efficiency, the more effective the electrical system is at converting input power into useful output power.
AC is better than DC for electrical power transmission because it can be easily converted to different voltages using transformers, allowing for efficient long-distance transmission with minimal power loss. Additionally, AC can be easily generated and distributed in power grids, making it more practical for widespread use.
If the efficiency is 0.5, then the useful lifting power is 0.5 of the powerthat it must consume in order to do the job.2,500 W = 0.5 of input power.input power = 2,500 / 0.5 = 5 KW.
AC current is considered better than DC current for electrical power distribution and transmission because it can be easily converted to different voltage levels using transformers, allowing for efficient long-distance transmission. Additionally, AC current is able to travel over long distances with minimal power loss, making it more practical for widespread distribution of electricity.
Energy is lost in hydroelectric power generation through factors such as friction in turbines, resistance in transmission lines, and inefficiencies in the conversion of kinetic energy into electrical energy. These losses reduce the overall efficiency of hydroelectric power plants.

Electrical transmission lines do have reactance, but it is not necessary for power to flow. In fact, the smaller the reactance, the higher the efficiency of the transmission system. Reactive power is not delivered to the load, it does no useful work, it just costs money to generate and causes heating of the conductors.
Moving electrical power from generating point to use point.
Electrical transmission towers are meant to hold the power lines and to carry electricity.
Energy efficiency is the ratio between the useful power, and the electrical power used. If this ratio is - for example - 70%, that means that the remaining 30% of the input power is wasted.
If the efficiency is 0.5, then the useful lifting power is 0.5 of the powerthat it must consume in order to do the job.2,500 W = 0.5 of input power.input power = 2,500 / 0.5 = 5 KW.
The efficiency of a device in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed. Scroll down to related links and look at "Electrical efficiency - Wikipedia".
To support the power lines. A power line is connected from the electrical transmission tower to the transformer to help bring electricity to the generator.

Energy is lost from power transmission cables due to resistance in the materials used to make the cables. When electricity flows through the cables, some of the energy is converted to heat as it encounters resistance, causing a loss of efficiency in transmitting power over long distances.
