The loss of electrical power in transmission lines, also known as line loss, is a significant issue in both Alternating Current (AC) and Direct Current (DC) power transmission. It involves the interplay of various factors such as the power or current driven on the line, wire length, voltage level, and wire gauge. This topic falls under the fields of Electromagnetism and Electrical Engineering.

Transmission line loss can be calculated using the following formula:
Where:
The formula is a direct application of Ohm's law, which was named after the German physicist Georg Simon Ohm. He first formulated the law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points, in the early 19th century.
Understanding transmission line loss is crucial for power engineers who design and manage power grids. It helps them choose the right parameters, like voltage level and wire gauge, to minimize power loss and ensure efficient power transmission. For example, this is why high-voltage transmission lines are used for long-distance power transmission - to minimize line loss.
Georg Simon Ohm made significant contributions to the field of electromagnetism by establishing Ohm's law. His work set the foundation for electrical engineering and has been instrumental in advancing our understanding of electrical circuits and power transmission.
Understanding the loss in AC/DC electrical power transmission lines and the associated calculations is crucial in the field of Electromagnetism and Electrical Engineering. With these concepts, we can improve the efficiency of power transmission, leading to more reliable and sustainable electricity supply systems.
