Electricity & Materials
A continuous flow of
negative charges is
otherwise known as
what?
Electricity & Materials
Electricity
Electricity & Materials
What are the TWO
units that are used
to measure
electricity?
Electricity & Materials
Voltage and Amperes
(Volts and Amps)
Electricity & Materials
What is the
voltage of
a common
DRY CELL
battery?
Electricity & Materials
1.5 VOLTS
Electricity & Materials
What is a DRY
CELL?
Describe it.
Electricity & Materials
A dry cell is a type of
battery that contains
chemicals in the
form of a paste.
Electricity & Materials
What is a WET CELL?
Describe it.
Electricity & Materials
A wet cell is a battery
that contains
chemicals in the
form of a liquid.
Electricity & Materials
What is a
CONDUCTOR
?
Electricity & Materials
A conductor is a type of
material that EASILY
allows electricity to
flow through it.
(Usually a METAL)
Electricity & Materials
What is an
INSULATOR?
Electricity & Materials
An insulator is a material
that DOES NOT ALLOW
electricity to flow
through it.
(usually a
plastic or rubber)
Electricity & Materials
The path taken by an
electric current is known
as what?
Electricity & Materials
A Circuit
Electricity & Materials
What three
things must a
circuit have
to work?
Electricity & Materials
1. An energy source (battery)
2. Wire so the current can
move.
3. Something to use the
electricity. (Light Bulb)
Electricity & Materials
What is a
closed circuit?
Electricity & Materials
A circuit that
can work. (It
allows the
movement of
electricity)
Electricity & Materials
What is an
open circuit?
Electricity & Materials
It is a circuit that is
“broken” or not complete,
so the electricity cannot
travel completely
through.
Electricity & Materials
What is a
SERIES circuit?
Electricity & Materials
It is a circuit
where the
electricity only
has one path
to follow.
Electricity & Materials
What is a
parallel
circuit?
Electricity & Materials
A type of circuit
where the electricity
has more than one
path to follow.
Electricity & Materials
In a magnet,
where is the
magnetic force
the greatest?
Electricity & Materials
Around the poles
(top and bottom)
