Circuits

Why won’t the light bulb in the circuit pictured to the right light up?

• The wires from the second light bulb are not connected to the battery

• The wires are not connected between the light bulbs 

• The wires are not connected to both sides of the first light bulb

• The wires are too long to complete the circuit 

What kind of circuit is this?

• series

• parallel

What material would be safest to use as an insulator to cover electrical wires?

• rubber

• tin

• aluminum

• water

What is a Parallel circuit? 

• Has only one path 

• Has more than one path 

• Allows energy to travel through easily 

• Has only one light bulb

An incomplete circuit is shown.
To complete the circuit, a wire should be placed from —

• Point D to Point C

• Point B to Point C

• Point A to Point D

• Point B to Point D

This circuit has a battery, buzzer, and switch.
When the switch is closed the buzzer will sound because -

• the switch gives energy to the battery

• the buzzer is made of special plastic

• the wires are cooled by the surrounding air

• electricity can flow in a complete path
