Modern physics of the 20th century was studying electromagnetism.

Whenever there is both an electric field and a magnetic field, there is a flow of energy. That is, there is no energy consumption in a state where only one exists. And the consumed energy can be calculated using the
Electromagnetism
and the
Poynting Vector
.

Field is main Actor

Energy is transmitted not through electrons or photons, but through fields.
Electromagnetism arises from the electrons and atomic nuclei within an atom, electricity appears with electric charge, and magnetism appears with electron clouds (Spin around atomic nucleus). Spin represents magnetic property and electric charge represents electronic property.

How Electricity Actually Works
전기 에너지는 전선으로 전달되는게 아닐...껄....요...?
전기 에너지가 전달된다는 것은 사실 전선으로 전달되는 것이 아닙니다..!? 기본 상식으로 알고 있던 사실이 깨진 기분이 드시진 않나요? 다음 영상도 전기 에너지에 대한 영상으로 찾아오겠습니다. 이 영상 꿀잼이에요. #전기 #에너지 #꿀잼 거대한 회로에 대한 더 자세한 분석은 해당 링크에 있습니다.
