1.5 V
4. 4. Two light bulbs are in series. One is unscrewed.
What happens to the other one?
It also goes
It gets brighther
Nothing happens
It blinks on and off
5. 5. What is true about the Earth's magnetic North
Pole?
It is the same as the
Earth’s geographic North pole.

It is actually a south
pole.
None of these are true.
6. 6. This symbol, a plain rectangle, is the electrical
representation of a:
Resistor
Wire
Battery
Capacitor
7. 7. Two light bulbs are in parallel. If the top bulb
is unscrewed, what happens to the other bulb?
Nothing
It gets dimmer
It gets brighter
It also goes out
8. 8. The pointy end of a compass needle is:
South
Negative
North
Not polarized
9. 9. What is wrong with this picture? (Compass needle/North end pointed toward
south pole of magnet.)
Compass needle should be
pointed left
Compass needle should be
pointed up
Compass needle should be
spinning around constantly.
The image is correct as it
is
10. 10. What causes
electromagnetism?
Magnetite
Rubbing a plastic rod with
fur
Electrical current
traveling through a wire
Two different metals in
acid
11. 11. A 6 volt
battery is connected to a 2-ohm resistor. What current travels through the
resistor?
12 amps
1/3 amp
8 amps
3 amps
12. 12. In a circuit,
what does this symbol represent? (Long
line and short line, parallel to each other)
Battery
Wire
Resistor
Diode
13. 13. When a magnet
moves through a coil of wire, what happens?
Nothing
Electrical current is
generated
Resistance is increased
The coil moves
14. 14. What has more
resistance: 2 identical bulbs in series, or the same 2 bulbs in parallel?
Both arrangements have the
same resistance
Series bulbs have more
resistance
Parallel bulbs have more
resistance
There is not enough information
to tell
15. 15. All bulbs are
identical - 2 bulbs in series vs. 2 bulbs in parallel. Which will glow brightest: series or parallel bulbs?
Series
Parallel
Both have the same
brightness
16. 16. Two charges
are separated by a distance. If the distance between them is doubled, force
will:
Also double
Not change
Be half as much
Be ¼ as much
17. 17. The atomic
number for an element, its order in the periodic table, indicates:
How many neutrons are in
the nucleus
How much binding energy is
in the atom
How many protons are in
the nucleus
How many electrons are in
the nucleus
18. 18. Which particle
is easiest to move in any atom?
Electron
Neutron
Proton
Quark
19. 19. The two
pointer stars at the end of the "scoop" part of the Big Dipper can
help you find:
Orion
The Milky Way
Sirius
The North Star, Polaris
20. 20. The opposite
of a motor is:
Battery
Electromagnet
Speaker
Generator
