Remove a battery.
A lab team constructed a circuit using three different-colored
light-emitting diodes (LEDs). Which bulb will most likely light if
Switch 3 is closed and the other switches are left open?
green
yellow
blue
If the switch were opened, which bulbs would still light?
Bulbs 1 and 3 only
Bulb 2 only
All three bulbs
None of the bulbs
The circuit shown uses a battery to power a motor. What form of energy
is the motor primarily used for?
sound
mechanical
light
thermal
In some circuits used for decorating, one burned-out bulb prevents the other bulbs from lighting. In other circuits, one burned-out bulb has no effect on other bulbs. In which of these circuits will other bulbs
light even if one bulb is burned out?

A student built the circuit shown. Why doesn’t the lightbulb glow?
The lightbulb is not part of a closed circuit.
The buzzer is using too much energy from
the battery.
The circuit needs a closed switch between
the buzzer and the battery.
The lightbulb is in contact with too many
wires.
All five of the lightbulbs in this circuit are lit.
Removing which wire would result in exactly
three bulbs being lit?
Wire 1
Wire 2
Wire 3
Wire 4
The circuit shown above does not work. Which procedure would most likely allow LED 4 to light?
Connect the non-wired end of LED 4 to the positive
end of the battery.
Close the switch.
Connect the non-wired end of LED 4 to the wired end
of LED 4.
Connect the non-wired end of LED 4 to the negative
end of the battery.
All the bells in this circuit are ringing. Which bell(s) would ring if Wire X were removed?
