What is an
electric circuit?

ELECTRIC CIRCUIT
•It is a
continuous
path over
which
electrons
move.

PARTS OF AN ELECTRIC CIRCUIT
LOAD
SWITCH
SOURCE
CONDUCTOR

LOAD
The part of
a circuit
that
consumes or
uses the
electricity

SOURCE
The part of
a circuit
that
provides the
electrical
energy.

CONDUCTOR
Electrical
wire where
electricity
flows.
Copper Wires
(Conductor)
Rubber or plastic (Insulator)

• An insulator is what
makes electricity from
not flowing
• Examples of insulators
are:
• Cotton
• Paper
• Plastic
• Glass
• Rubber
• Cloth
• A conductor is something
which allows electricity to
flow through.
• Examples of conductors
are:
• Scissors
• Paper clip
• Aluminum foil
• Iron
• Steel
• Copper
• Water

SWITCH
A convenient
device that
opens and
closes the
circuit. (turns
the circuit on
and off).

BASIC TYPES
OF A CIRCUIT

SERIES CIRCUIT
Type of circuit
that has only one
pathway of
electricity. When
one part is loosen
or disconnected,
other parts will no
longer work.

PARALLEL CIRCUIT
Type of circuit
with two or
more pathways
of electricity
and each is
independent to
one another.
