SUMMARY
The discussion centers on the efficiency of electric power transmission from power plants to homes using high voltage. It is established that higher voltage reduces current, which in turn minimizes power losses in transmission lines due to resistance. The relationship between power (P), voltage (V), and current (I) is defined by the equations P = VI and P_loss = I²R, demonstrating that increasing voltage while maintaining power results in lower current and significantly reduced losses. Additionally, transformers play a crucial role in adjusting voltage levels for efficient transmission and distribution.
