Electrical Circuits Day 6

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 and 3, leave switch 2 open

• 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

• Light bulb 1 will be off, but light bulb 2 will be on

• Light bulb 1 and light bulb 2 will both be off

• Light bulb 1 will be on, but light bulb 2 will be off
