I watched Veritasium's video on big misconceptions of electricity, i remember when we learn how does lamp light up in the circuit, our teacher said it is the kinetic energy of electrons transfer to metal ion of filament lamp, then convert to heat and light. but in the video, it talked about poynting vertor, does that mean the energy is transferred to the lamp in electromagnetic radiation form?

In a simple electric circuit with battery and lamp, how does the lamp light up?
