What is a circuit?
A circuit is the pathway taken
by electric current.

4.3
What do closed circuits do?
4.3
Closed circuits allow the
movement of electrical energy.
4.3
What do open circuits do?
4.3
Open circuits prevent the flow
of electrical movement.
4.3
What are conductors?
4.3
A continuous flow of negative
charges (electrons) creates an
electric current.
Conductors are materials that
allow the flow of electrical
energy. (metals)

What are insulators?
4.3
4.3
What is a series circuit?
4.3
A series circuit has only one
pathway for the current.
4.3
What is a parallel circuit?
4.3
A parallel circuit has two or
more pathways for the
electrical current to run
through.
4.3
What is static electricity?
Static electricity is created
when certain materials are
rubbed together.

4.3
What is lightning?
4.3
Insulators prevent the flow of
electrical energy. (rubber,
plastic, wood)
Lightning is the discharge of
static electricity in the
atmosphere.

4.3 Force, Motion, and Energy
Electrical energy can be
transformed into light, or
motion, and can produce
thermal energy.
What can electrical energy be
transformed into?

4.3
What is the magnetic force?
4.3
The magnetic force is the line
of force that extends from
the poles of a magnet in an
arched pattern.
4.3
What creates a magnetic
field?
4.3
Electric current creates a
magnetic field.
4.3
What creates an electric
current?
4.3
A moving magnetic field
creates an electric current.

What does a current flowing
through a wire create?
4.3
A current flowing through a
wire creates a magnetic field.
4.3
How can you make a magnetic
field?
4.3
You can make a magnetic field
by wrapping a wire around an
iron nail and creating a closed
circuit.

What is an electromagnet?
4.3
An electromagnet is an
arrangement of wire wrapped
around a core, producing a
temporary magnet.
