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.

What challenges were faced with transporting direct current (DC) over long distances?

Explain the role of the magnetic field in the operation of a transformer.
