MATERIALS AND FORMS OF ELECTRICITY

Science6th

MATERIALS

• We can classify materials in two groups:

• CONDUCTORS This is a material which allows electricity to flow easily.

• INSULATORS This is a material which doesn’t allow electricity to flow easily.

FORMS OF ELECTRICITY

• Static electricity is the form of electricity that doesn’t flow. Electrical storms are an example of this static electricity. Ice particles in the clouds move very fast and rub together. This causes a huge amount of energy to convert into light, heat and sound.

• Current electricity is the movement of electrons from one object to another. It can be produced in a closed electrical circuit.

ELECTRICAL CIRCUIT

• An electrical circuit has the following parts:• GENERATOR/BATTERY it provides energy.• CONDUCTOR it is a wire that lets the

electricity flow through the electric circuit.• ELECTRICAL COMPONENTS it changes

electricity into another form of energy.• SWITCH it opens and closes the circuit.
