What type of current comes out
of batteries?
A 100
Dc or direct current
A 100
In metals, electric current
is the actual flow of
A 200
Electrons
A 200
A short circuit
occurs when
A 300
the positive wire is connected
directly to the negative wire
A 300
The total resistance
of a three10-ohm
resistors in parallel
is
A 400
3.33 using 1/
1/10 + 1/10 + 1/10
A 400
True or False
significant current will flow in
a insulating material when
there is a difference in
potential between the ends of
that material
A 500
False, too much
resistance so no current
A 500
What comes first, voltage or
current?
B 100
Voltage! Charges are given a
push and if not too much
resistance, will create current.
B 100
How is work related to electric
Potential Difference?
B 200
Work = q*V
Voltage is energy or work done
/charge
B 200
If you have a straight wire
hooked up to a battery, which
“hand” equation do you use?
B 300
First or second using thumb as
wire, fingers curled as magnetic
field
B 300
How do you find energy from
power?
B 400
Energy = power * time
B 400
When measuring
current, you place the
ammeter in ____
B 500
Series: so collect all current
B 500
If two like charges are
pulled further apart, what
happens to their total
electric potential energy?
C 100
The electrical potential energy
decreases to a lower more
favorable energy as they
repel another and would
rather be apart
C 100
What sort of field(s)
exist around a moving
charge?
C 200
Both electric (it’s a charge) and magnetic (moving
charge) fields
C 200
Which is true of magnetic but not Electric field lines…
Lines move from higher to lower energy
Lines stop and start , not continuous
Lines give direction of force
Lines never cross another.
C 300
Stop and start- magnet lines go
forever in continuous loops.

C 400
When will a current carrying a
wire experience a magnetic
force?
C 400
When it is in a changing
magnetic field
C 400
What is the difference
between conduction and
induction?
C 500
Conduction involves contact with the
charged source. Induction has no
contact with the source but does have
grounding.
C 500
A device that converts electric
energy into mechanical energy is
a(n)
D 100
electric motor
D 100
When an iron rod is inserted
into a solenoid’s center, the
magnetic field produced by
the current in the loops
D 200
causes alignment of the
domains in the iron.
D 200
What are domains?
D 300
Regions within an atom where
the atomic magnets point in the
same direction
D 300
What are advantages of
a permanent magnet
over an electromagnet?
D 400
It won’t quit when power
fails and is much simpler
D 400
How can you strengthen an
electromagnet?
D 500
increase number of coils,
insert an iron bar, stronger
battery
D 500
What is a E-Field?
E 100
An electric field shows the
direction a positive charge
would be pushed due to
the presence of charged
objects.
E 100
Where do field lines
originate, at a positive or
a negative?
E 200
They begin at a positive and
end on a negative.

A polarized
object has
what kind of
charge?
E 400
None- just A temporary separation of Charges
So still neutral
E 400
What charges can a neutral object
not attract?
E 500
Another neutral.
Neutrals do attract + and charges
