a familiar form of energy
energy required to operate
appliances, devices, gadgets
and machines
atoms are neutral (no charge)
the number of positive and
negative particles are equal
some objects can lose electrons
and some can gain electrons.
why only electron is
transferred???
the number of protons and
electrons are not anymore equal
there is more proton compared to
electrons
so the objects is said to be
POSITIVELY CHARGED
the number of protons and
electrons are not anymore equal
there is more electrons compared
to protons
so the objects is said to be
NEGATIVELY CHARGED
the number of electrons lost is
always equal to the number of
electrons gained.
LAW OF CONSERVATION OF
CHARGE
Charges cannot be
created nor destroyed,
but can be transferred
from one material to
another.
an invisible force acting on charge
materials or objects
attract
repel
Like charges repel and
opposite charges
attract.
happens when a neutral object is
place near a charge object
charges in the neutral object
rearrange such that opposite
charges are brought near each
other
the process of removing excess
charges on an object
providing a ground
any object that can be a source of
unlimited electrons in order to
neutralize the charged object
GROUNDING
happens when two objects are in
direct contact
as object rapidly strip away, one
loses electron and the other gains
electron
a material that permits chargers
to flow freely within it
metals are usually good
conductors of electricity
are materials that hinder the flow
of charges
examples are glass, porcelain,
plastic and rubber
process wherein an object is
charged without actual contact to
any other charged object
process wherein a neutral object
is charged by direct contact with a
charged object
a path through which charges can
flow
