CA, CC y transformadores

The video explains the evolution of electricity from direct current (DC) to alternating current (AC), highlighting the limitations of DC in long-distance power transmission due to heating losses. AC's ability to change direction allows for voltage adjustments, enabling efficient long-distance transmission. Transformers play a crucial role in modifying voltage levels, allowing high-voltage transmission and safe domestic use. Step-down transformers reduce voltage for home use, ensuring safety and efficiency.
