Circuits

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

What is a circuit with several paths for electricity to flow?

• conductor

• series circuit

• parallel circuit

• open circuit

What is a circuit that only has ONE path for electricity to flow?

• series circuit

• closed circuit

• parallel circuit

• 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
