How Electrical Energy Travels Through a Circuit
Veritasium · Explainer · YouTube title: How Electricity Actually Works
Why it's here
HN cites it for the field-based picture of power transfer, noting it was controversial at release but the experiment largely backed the creator.
What it covers
Veritasium explores how electrical energy actually travels in a circuit, arguing that it flows through electromagnetic fields around the wires rather than through the electrons. It builds a long-cable experiment with Caltech to test when a distant bulb lights.
