ELECTRICITY

• Electricity is an important part of our life. Since electricity is a form of energy, it is capable of doing work.

• Static Electricity-

Is the accumulation of electric charges on an object.

Electrically charged objects obey this rule- opposite charges attract, like charges repel.

• Electric Current- The flow of electric charges.

Conductors and Insulators

• Conductors- Materials that allow electrons

to move easily through it. Current moves through

conductors because electrons can move easily through materials that do not hold their electrons tightly.

Copper, aluminum, and silver are good conductors.

• Insulators- Materials that do not

allow electrons to move through it easily.

Plastic and rubber are good insulators.

• Electromagnetic Induction- Is the process in which

the motion of wire through a magnetic field produces a current.

Most of the electrical energy converted to useful electricity by electromagnet induction.

ENERGY CONSUMPTION AND CONSERVATION

• ENERGY CONSUMERS MAY BE DIVIDED INTO RESIDENTIAL,COMMERCIAL,INDUSTRIAL AND TRANSPORTATION SECTORS

Turn off the light when it is not used.

Unplug the appliances when it is not used.

Use public transportation instead of privately-owned vehicles as much as

possible.

Recycle materials

Ride bicycles or walk on short strips. Avoid unnecessary trips.
