Veritasium Is Wrong. The Energy Probably Flows Through The Wires. Quantum Field Theory Says So.

A  couple of weeks ago Derrick Muller of the YouTube Channel Veritasium made a video asserting that the electrical energy in a circuit does not flow through the wires but through the fields. This is true and yet also a misleading misconception. This misco ...
