Sometimes we have felt a shock when walking on a carpet and soon to touch a metal object. Is this due to the electricity est? tica Basta with rubbing a body and obtaining ace? electricity. In this experiment we will be able to illuminate a fluorescent tube with the electricity obtained when rubbing a rubber globe.
Qu? it is needed?
|C? does mo become?
1. - Inflated is a globe and once tied rub does it with a piece of pa? or of wool, also diverse fabric pieces can be used.2. - Subject with a hand one of the ends of the tube and with the other it approaches the electrified globe on the other extreme.
You observe light within the tube? If you do not see it, dull the light and repeats the experiment with.3. - Subject with a hand the part met? lica of one of the ends of the tube and with the other approaches the electrified globe on the other extreme (it approaches the ends).
You observe that the tube is illuminated by a brief moment?
The interesting thing is that this experiment you can do it with a burned fluorescent tube!
By qu? it happens this?
? do volumes that form the matter have some part? culas calls electrons that turn in his? does rbitas, when rubbing take place one descompensaci? does n because it leaves from electrons of a body happen to the other, we secured ace? what by definici? n is electricity. Is this type of electricity called Est? tica and is accumulated in the surface of the globe. Does the fluorescent tube contain an inert gas that when it receives a unloading? does ctrica, when approaching the globe, take place a luminescence because? do volumes in the gas have electrons that leave his? rbitas forced by the unloading and when returning to his? rbitas does it dismissing photons, that is to say light.
