the electrical activity of an atom is the same electricity of a light bulb?
What do mean by electrical activity of an atom? In general electricity is described by electron motion - for example in a light bulb, the electrons move around fast enough to heat up the filament.
Not to question you sir but isn't the light bulb a reaction process where the resistance of the filament and the amount of voltage through the circuit (not the speed in which electrons move around) is the reason for illumination?
You're probably right. What I have in mind is that the electrons are jittering, so as you increase voltage they jitter more.
