AC, DC and Transformers

The video explains how electricity is supplied to homes, highlighting the transition from direct current (DC) to alternating current (AC) due to DC's inefficiency in long-distance transmission. AC allows for voltage stepping up, reducing current and power loss. Transformers play a crucial role in adjusting voltage levels for safe home use, enabling efficient electricity distribution through national grids.
