electricity
Electricity is the presence or flow of charged
particles.(electrons)

flow
The movement of electrons through a conductor.
electrons
Negatively charged particle
complete
circuit
There is no gaps present and the circuit will function (the
bulb lights up.)
incomplete
circuit
filament
light bulb
An old fashioned light bulb that produces store heat
energy than light energy.
It is inefficient.
florescent light – white

electrical
conductor
A material that allows electricity/current electrons to flow.
electrical
insulator
A material that resist/does not allow electricity/current
electrons to flow.

current
The rate of flow of electrons
ammeter
A measuring equipment/device that measures current.
amperes
In short amps. Unit for current.

My
explanation
The
current in
a series
circuit is
the same
anywher
e in the
circuit.
Current is
the same,
throughout
the circuit =
0.15A
When
the
number
of
batteries
is
doubled,
the
current in
a series
circuit
doubles.
0.6A
The
greater
the
voltage
the
greater
the
current.
The
batteries
must all
be
connecte
d in the
same
direction.
If not
they will
cancel
out.
The same
terminals
should not
face each
other.
The
more
bulbs in
a series
circuit,
the
dimmer
the
bulbs.
Current
decreases
when more
components
are added

Weak
conductor:

ncil because
it resists the
flow of
electrons.
Two
bulbs in
a series
circuit
are not
as bright
as two
bulbs in
a parallel
circuit.
Series brightness
are unequal
- depending
on the
resistance of
the bulb.

Parallel brightness
are equal

The
electrons
flow out
of the
negative
end and
back into
the
positive
end of
the
battery.
