Do bulbs convert moving charge to light?

In a light bulb, the electric potential energy of the charge is transformed into light energy (a useful form) and thermal energy (a non-useful form). The moving charge is doing work upon the light bulb to produce two different forms of energy.

Explanation:

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
