Physical Sciences-Electricity
Electrical energy can be transferred and transformed in electrical circuits and can be generated from a range of sources (ACSSU097)
Elaborations
Elaborations
- recognising the need for a complete circuit to allow the flow of electricity
- investigating different electrical conductors and insulators
- exploring the features of electrical devices such as switches and light globes
- investigating how moving air and water can turn turbines to generate electricity
- investigating the use of solar panels
- considering whether an energy source is sustainable

CONDUCTORS AND INSULATORS
Conductors
Some materials let electricity pass through them easily. These materials are known as electrical conductors.
Many metals, such as copper, iron and steel, are good electrical conductors.
That is why the parts of electrical objects that need to let electricity pass through are always made of metal.
Metal is used in plugs to allow electricity to transfer from the wall socket, through the plug, and into a device such as a radio or TV.
In a light bulb, the metal filament conducts electricity and causes the light bulb to light up.
Insulators
Some materials do not allow electricity to pass through them. These materials are known as electrical insulators.
Plastic, wood, glass and rubber are good electrical insulators.
That is why they are used to cover materials that carry electricity.
The plastic covering that surrounds the wires is an electrical insulator.
It stops you from getting an electrical shock.
