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 collection of hundreds of tiny circuits that supply electric current to the various
parts of an electronic device.
Circuit Board
Integrated Circuit Board
• An entire circuit containing many transistors and other electronic components formed on a single chip
• Found on semi-conductors
• 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
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
