Electrical Circuits Day 9

Observe the circuit below. If the students connect a wire between bell 2 and bell 4, which of the bells will ring?

• Bells 1 and 3

• Bells 1 and 4

• Bells 1, 2, and 4

• Bells 1, 3, and 4

A group of students constructed the circuit with colored light bulbs. If switch 1 was closed which bulbs will glow

• The red and blue bulb will glow and the white will not glow

• The blue and white bulb will glow and the red will not glow

• All the bulbs will glow

• The red and white bulb will glow and the blue bulb will not glow

Students constructed the circuit above. What would the students have to do in order to make the bell ring?

• Close swtich 1

• Close 2 and 3 and leave switch 1 open

• Replace switch 1 with a metal spoon and leave switch 2 and 3 open

• Close switch 3 and leave switch 1 and 2 open

If the blue bulbs were replaced with closed switches, and switch 3 was replaced with a rubber band which appliances will function?

• All the appliances will function

• The green bulb will be the only appliance to function

• The bell will be the only appliance to function

• None of the appliances will function

The student place different objects in the gap and turn on the switch to see if the light bulb lights up. Which object will best conduct electricity?

• A glass bead because it allows electricity to flow through

• A plastic button because it allows electricity to flow through

• A copper coin because it allows electricity to flow through

• A wooden toothpick because it allows electricity to flow through

A group of students are conducting an investigation on circuits. The circuit below illustrates two light bulbs, a power source, and copper wires. Which would happen to the circuit if the students added an additional power source?

• The light bulbs will shine brighter

• The light bulbs will dim

• The copper wires will not allow electricity to flow to the light bulbs

• The additional power source will only light up one light bulb.

The picture shows an example of a simple circuit. The lightbulb will not light up because...

• there is no switch in the circuit.

• the wires do not form a closed circuit.

• the wires are too long.

• the lightbulb is broken.

Look carefully at the picture. Will the lightbulb light up in the circuit?

• No, because the circuit is not closed.

• Yes, because the penny is a good insulator.

• Yes, because the penny is a good conductor.

• No, because the penny blocks the flow of electricity.

Study the picture. Will any of the lightbulbs light up in this circuit if the switch remains open?

• No, the circuit isn't closed with the switch open.

• Yes, only Bulb 3 will light up.

• Yes, Bulbs 2 and 3 will light up.

• Yes, Bulbs 1 and 3 will light up.

Study the picture. Which lightbulbs will remain lit if the wire is cut at the point where the scissors are located?

• Bulb 1 only

• Bulbs 1 and 2

• Bulbs 2 and 3

• None of the bulbs
