Electricity & MagnetismWord Challenge

Some computer chips are made of a substance that conducts electric current better than an insulator but not as well as a

conductor.

These substances are often called _________

Other examples include:

transistors and diodes

Answer: Semi Conductor

This is a part of an electronic device that only allows current to flow in one direction.

Answer: Diode

A circuit offering only one possible

path for charges to flow

Series Circuit

This part of an electronic device can be used as an amplifier or switch.

Transistor

A collection of hundreds of tiny circuits that supply electric current to the various

parts of an electronic device.

Circuit Board

Electricity

• The flow of electrons from one point to another

Integrated Circuit Board

• An entire circuit containing many transistors and other electronic components formed on a single chip

• Found on semi-conductors

A circuit offering more

than one route for the flow of

charges

Parallel Circuit

• A closed path for electric current

Electrons travel from the negative positive

terminal of the battery.

Circuit

Alternating Current

• type of electric current in which charges continually switch from flowing in one direction to flowing in the reverse direction

AC

Conduction

• the transfer of electrons from one object to another through direct contact

Static Electricity

• the build-up of electric charges on an object

Insulators

• a material, such as wood, glass, or plastic, that does not allow charges to flow easily; any material which poorly transfers energy

Induction

• the transfer of charges from one object to another without direct contact

Direct Current

• type of electric current in which the charges always flow in the same direction.

DC

Conductors

• a material that allows charges (like electrical current) to flow easily; any material which easily transfers energy
