U
ST
, Electricity - ANS Energy due to electric charges at rest or in motion that can be transmitted to
produce effects such as heat, light, motion or sound.
Electric Charge - ANS An electrical property of matter that creates electric and magnetic forces
and interactions.
Positive (+) - ANS An electric field lacking electrons.
Negative (-) - ANS An electric field containing large quantities of electrons.
K
Voltaic Pile - ANS Stacked pairs of unlike metals for increasing the intensity of an electric
charge.
C
Electromagnetism - ANS Magnetic effects introduced by the flow of charge or current.
Faraday's Law - ANS The generation of voltage increases with additional flux or a faster rate of
LO
charge of the flux field.
Geissler Tube - ANS A sealed glass tube with platinum connections at the ends, containing
rarefied gas made luminous by an electrical discharge.
YC
Diode - ANS A semiconductor device with two terminals, typically allowing the flow of current in
one direction only.
Triode Tube - ANS A device that amplifies a signal so it can be heard on both ends of the
transmission. This created reliable point to point communication and broadcasting.
D
Transistor - ANS A three terminal semiconductor used in a circuit as an amplifier or switch.
Semiconductor - ANS An element or compound that conducts electric current better than an
U
insulator does but not as well as a conductor does.
Integrated Circuit (IC) - ANS An electronic circuit having many components, such as
ST
transistors, diodes, resistors, and capacitors, in a single package.
Microprocessor - ANS An integrated circuit semiconductor device that performs arithmetic,
logic and control functions in a microcomputer.
Vaccum Tube - ANS A device that controls electric current flow in a high vaccum between
electrodes to which an electric potential difference has been applied.
Electro-Mechanical - ANS A mechanical processs or device that is controlled electrically.
