Science-Circuits

This circuit is.....

• open

• closed

• parallel

• showing the flow of electricity

When all parts of the circuit are connected it is a/an ....... circuit.

• open

• closed

With which group of items could you not build a complete circuit?

• Crocodile leads, bulbs, switch, buzzer

• Bulbs, crocodile leads, cell

• Cell, switch, buzzer, crocodile leads

• Wires, bulb, cell

What symbol is used in a circuit diagram to represent a bulb?

• A circle

• Two parallel lines: one short and one long

• An X inside a circle

• The letter M inside a circle

What will a circuit with an open switch do?

• It will not allow electricity to pass through

• It will allow electricity to pass through

• It will resist electricity

• It will make a good electrical insulator

A material which allows electrical current to pass through it is called what?

• An insulator

• A cell

• A connection

• A conductor

What is an electrical circuit?

• A collection of electrical equipment

• A path around which electrical current flows

• A series of conductors and insulators

• A light bulb and battery

Why are electrical wires covered with plastic or rubber?

• Plastic and rubber are comfortable materials to touch

• Smooth materials keep wires from getting tangled

• Plastic and rubber are good electrical insulators

• Plastic and rubber can be made in different colours so people can tell different leads apart

Which of these materials would not be a good electrical conductor?

• Copper

• Glass

• Silver

• Iron

Why might a circuit fail to work?

• It might have a dead battery

• It might have two leads connected to the positive pole of the battery and none connected to the negative

• It might have a break in the circuit

• All of the above
