Topic 1 - Electrical energy can be transferred and stored

• Opposite charges attract each other - Like charges repel each other

• Sudden transfer of electrical charge from one object to another.

The concentration of like charges in specific areas of a neutral object, happens by approach of charged object.

Reliable flow of charged particles. (it does flow)

It is moved through the movement of electrons

Path which controls the flow of electricity. Things found: conductor load, switch etc.

Amperes

Electricity which is manufactured or produced by a specific organ in the tail which involves thousands of modified cells.

Energy transported by charged particles.

Measure of how much electrical energy charged particle carries. Another name for Voltage is Potential Difference

VOLT

Through a voltmeter

Unintentional low-resistance connection between two points in a circuit usually causing excess current to flow.

Voltages because a lot of electrical energy.

They make it difficult for electrons to flow through them. Examples: wood, rubber, air or eraser

• Never hold electrical devices when you are wet or nearby water except they are specifically made and accepted for use in wet zones or areas. • Do not utilize any power cord which is frayed or broken. • Always unplug electrical devices before looking inside them. • Do not weigh down circuits by plugging in and operating several devices. • Stay away from power lines. • Do not neglect safety features formed into home wiring, appliances, and other electrical devices. • When unplugging a device, pull on the plug, not electrical cord. • Never get rid of the third prong from a three prong plug.

A thin piece of metal which melts to break an electrical circuit when excess current flow happens.

• A peculiar or special wire which heats up and turns off switch when excess curent flow through electrical circuit.

To break an electrical circuit when excess current flow happens.

Bundle of chemicals which are designed to manufacture small amounts of electricity; produces electricity from chemical reactions.

cell which has its electrolyte in the form of paste, often in a sealed case. Example: A Flashlight

Paste or liquid which conduct electricity since it includes chemicals that create ions.

Liquid electrolyte. Example: A car battery

Cell which produces electricity by means of a chemical reaction which cannot go back to its original form.
