1. UNIT 5 ELECTRICITY AND MAGNETISM

2. Why do you think wires are built this way?
Electrical currents
Why do you think wires are built this way?
They allow current to flow but need to be safe to handle

3. ELECTRICAL CURRENT CONDUCTORS INSULATORS
It is the flow of electrical charges. Transmits energy called electricity. Depending on the materials it flows differently.
CONDUCTORS
INSULATORS
AIR, GLASS, PLASTIC, WOOD, RUBBER
Electrical current does not flow easily
MOST METALS
Current flows easily

4. Electrical circuits

In the on position,_____________________________
___________________________________________
In the off position_____________________________

14. Write about electric circuits
An electric circuit has four basic components: a generator, an electrical component, conducting wires and a switch.
They are connected to each other to allow the flow of an electrical current. .
A switch controls the flow of electrical current.
In the on position, it closes the circuit and allows the flow of the electrical current. In the off position, it opens the circuit and breaks the flow.
