electricity Flashcards
proton
neutron
electron
positively charged particle inside the nucleus
neutral particle locket in the nucleus of the atom
negatively charged particle rotating around the atoms nucleus
transfer of charge
when electrons transfer from one object to another
charging to make a neutral object charged or to change the charge of a charged object
friction
two different materials rubbed together
electrons go from one to another
contact
two objects touch and the electrons travel from one to the other
induction
a charged object comes close but doesn’t touch the other object but a charge is still induced
conductors
materials that allow electrons to flow through them with ease
they cannot be easily charged by friction as extra electrons that are gained can easily escape
insulators
materials that do not allow electrons to flow through them easily charged by friction
but the electrons cannot easily escape
static electricity
is an imbalance of electric charges on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge.
positively charged atom
negatively charged atom
neutral atom
more protons then electrons
more electrons than protons
equal number of protons and electrons
all of this is the same for objects over just atoms instead of pro and electrons
rules of charging
if there are two negatively charged objects they will repel each other
two positively charged will repel
one negative and one positive will attract
a neural and a charged will attract
