Electric Circuits

What is a conductor

• material which allows electricity to pass

• material which does NOT allow electricity to pass

• material that is sticky

• material that is wet

An insulator

• makes a spark

• is made of metal

• allows the flow of electricity

• stops the flow of electricity

Wires that go in a complete loop around the power source & back around again is a .......

• round circuit

• complete circuit

• off circuit

• blank circuit

What are the three items that make up a circuit

• power supply, wires, boot

• power supply, wires & book

• power supply, wires, device

• power supply, wires, sock

Name 2 power sources

• cells (batteries) & mains

• knives & forks

• sun & water

• plugs & radios

If a circuit is not complete, what happens

• it works

• it won't work

• it might work

• it plays a song

• coin

• plastic fork

• a key

• copper

Metals, coins, copper or steel are examples of

• insulators

• heavy things

• things that rust

• conductors

When a switch is in the "ON" position

• the circuit is incomplete

• electricity doesn't flow

• the circuit is complete

• you get a shock

By adding more bulbs to the circuit, the bulbs will become

• will shine brightly

• will turn off

• dim, (not shine as brightly)

• will blink
