The circuit does not work. Which procedure would most likely allow the bulbs to light?
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?
If the switch were opened, which bulbs would still light?
The circuit shown uses a battery to power a motor.
What form of energy is the motor primarily used for?
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?
How many bell(s) would ring if Wire X was removed?
This circuit has four light-emitting diode (LED) lights. It also has a battery and a switch.
Which LEDs produce light when the switch is in the position shown?
All the lightbulbs in this circuit are lit. How many would remain lit if Wire 5 was removed?
This circuit has four light-emitting diode (LED) lights. It also has a battery and a switch.
Which LEDs produce light when the switch is in the position shown?

Which LEDs produce light when the switch is in the position shown in the diagram?
All the bells in this circuit are ringing. Which bell(s) would ring if Wire X was removed?
All the lightbulbs in this circuit are lit. How many would remain lit if Wire 3 was removed?
A student built the circuit shown. Why doesn’t the lightbulb glow?
All five of the lightbulbs in this circuit are lit. Removing which wire would result in exactly
three bulbs being lit?
Which of the following list of electrical components could NOT be used to create a working circuit?
All the bells in this circuit are ringing. Which bell(s) would ring if Wire X was removed?
