Conductors and Insulators

Front

What is a conductor?

Back

A conductor is usually a metal, conducts heat, and can be a copper wire.

Front

An insulator

Back

Opposes electrical current meaning electric charges do not flow freely

Front

The best insulators are: Plastic, rubber, wood, glass, Silver, air, paper, silicon, Copper, aluminium, gold, steel, Ceramic, fabric, paper clip, cork

Back

Plastic, rubber, wood, glass

Front

Attached to this electrical circuit is copper. Copper is a conductor of electricity therefore the bulb should:
- Glow a lot brighter
- Turn off immediately
- Instantly get very hot, then cool down quickly
- Be dimmer

Back

Glow a lot brighter

Front

What is the conductor in the picture? Options: Light bulb, Battery, Wires, Switch

Back

Wires

Front

Why are the poles of a power line in our street made of wood?

Back

Wood is an insulator- they stop electrical current from the power lines hitting the ground

Front

What happens when a rubber tube with two alligator clips is attached to the circuit?

Back

The light bulb will not turn on and the ammeter will show a reading of 0 A because rubber is an insulator

Front

What is a conductor?

Back

Allows electricity to pass through it

Front

Which of these is not an electrical insulator: Wood, Plastic, Silver, Glass?

Back

Silver

Front

Which of the following is not an electrical conductor? Gold, Copper, Aluminium, Rubber

Back

Rubber
