A group of students is building a circuit represented in the diagram.

What object can be used at position x for the buzzer to sound when switch K is closed?

• A power source

• An insulated wire

• Another bulb

• Another switch

A student wants to make a change to the circuit shown so that when Switch 1 is open and Switch 2 is closed, only one light will be on in the circuit.

Which diagram shows how the student should change the circuit?

A student constructs the circuit shown for a science demonstration.

With the switches in the current positions, which lights are on?

• All the lights

• Lights 1 & 2

• Lights 3 & 4

• None of the lights

A student builds a circuit allowing the lightbulbs to light, the buzzers to make sound, and the motors to turn.

Which two switches can be open and still allow all of the parts to work?

• Switch 1 and 3

• Switch 1 and 4

• Switches 2 and 3

• Switches 3 and 4

The circuit has five light-emitting diode, or LED lights. It also has one battery and one switch.

Which LEDs produce light when the switch is in the position shown? (Multiple select)

• LED 1

• LED 2

• LED 3

• LED 4

• LED 5

The circuit does not work.

Which procedure would most likely allow the bulbs to light?

• Open the switch and then connect the two wires that are attached to the wood.

• Switch the positions of the two wires that are connected to the battery and then open the switch.

• Move the switch closer in the circuit to the battery.

• Connect the two wires that are attached to the wood block.

In some circuits that are used for decorating, one burned-out lightbulb will prevent all the other lightbulbs from lighting. In other circuits, one burned-out lightbulbs will have no effect on the other lightbulbs.

In which of these circuits will the other lightbulbs still light even if one bulb is burned out?
