Static Electricity Flashcards
Static electricity definition〽️
It is the build up of charge on a material. This kind of electric charge is called “static” because it stays in one place ❗️
Location of proton neautron and electron in nucleus
Nucleus nucleus and cloud
Charge of proton neutron and electron
Positive none and negative
Size of proton neutron neutrón and electron
1 amu, 1amu, -1amu (almost zero)
Who made 2 fluid theory
Charles Dufay
Who made one fluid theory
Benjamin Franklin
What was the 2 fluid theory❔
The theory that there can be Vitreous and Resinous fluids
Objects can have more vitreous than resinous fluid or vise versa, or they can be equal which makes an object electrically neutral
What was the 1 fluid theory? ❔
It was that he introduced the concept of objects having positive or negative charges ❗️
It’s the theory that states that an object can have an excess or deficiency of electrical fluid. If an object is completely filled with electrical fluid then it is neautral
+a negative object would have deficiency and a positive object would have an excess of the fluid
(Objects)Electrically:
neutral + neautral =?
=REPELLING
(Objects) electrically:
Positive + negative=?
=attract
Positive +positive=?
Repel
Negative +negative=?
=repel
Neutral+positive
=attract
Neutral +negative=?
=attract
Can protons leave an atom?
NO
Conductors ?
An object that allows electrons to flow through and spread across the whole surface
Insulators
An object that does NOT allow charge to flow through freely . If charge is transferred to an insulator the electrons stay there and don’t move from the inserted spot
What do opposite charges do when they come into contact
Attract
What do like charges do when coming into contact
Repel
Charging friction
Its when 2 objects are rubbed together the electrons clouds of the atoms on the surface are interacting then the stronger the pull, the more electrons transfer from other atoms to their Valente shells now both objects are charged
