ELECTRICITY Flashcards
a hardened translucent
yellowish tree resin that when you rubbed it with a piece of
cloth, could attract nearby objects.
amber
supported this idea that many
other substances possess the same ability as that of amber.
William Gilbert (1544-1603)
term William Gilbert used to refer to the phenomenon of amber
electrics
ability of amber
electricity
Greek word meaning “amber”
electron
This idea supported that any object when
being rubbed could attract small pieces of matter. This object
attracted is said to have acquired charge or electrified.
Electricity
is the
flow of electrons.
Electricity
an electrical property of matter that creates a force between objects
electric charge
study of all phenomena associated with electric charges at rest
electrostatic
the fundamental quantity of electricity.
Charge (q)
The
SI unit of charge
Coulomb (C)
the SI unit of charge was named after
Charles Augustin de Coulomb
1C = how many protons/electrons?
