NCATT AET ACTUAL TEST QUESTIONS
WITH COMPLETE ANSWER KEY
●● Faraday's Law
Answer: current will flow in a circuit provided there is electrical
difference in potential and there is a path for it to flow
●● Loads slow current by
Answer: applying resistance
●● Current flows from
Answer: negative to positive
●● Atoms
Answer: represent the smallest elements that exist in nature
●● Atoms are made up of
Answer: protons, neutrons and electrons
●● Nucleaus
Answer: center of the atom
,●● Electrons travel
Answer: at the speed of light
●● Protons
Answer: positively charged subatomic particles
●● Protons contain
Answer: a positive electrical potential
●● Protons positive charge
Answer: affect the orbits of the electrons
●● Neutrons are
Answer: neutral subatomic particles
●● Neutrons are not involved
Answer: in the conduction of electricity
●● Electron's charge
Answer: is negative
●● The speed of rotation combined with electrical potential
,Answer: keeps the electrons in their orbits
●● The attraction of opposite charges
Answer: holds the electron in its orbit
●● Conductors
Answer: easily permit the movement of electrons from an electrical
source to a load and back to the electrical source with a minimum of
resistance
●● First two inner orbits
Answer: make up the atomic number for the element
●● During conductance an extra valence electron
Answer: flows into the next atoms valance orbit
●● Good conductors
Answer: Only those elements that dont hang on to their valence
electrons
●● Good Insulators
Answer: Elements that don't give up valance electrons no matter what
force is applied
, ●● lators
Answer: a material or device used to prevent the passage of heat,
electricity or sound from one medium to another
●● Examples of insulators
Answer: Glass, Mica, Silica
●● Air
Answer: can be a good insulator but will spark when enough electrical
force is applied
●● Static Electricity
Answer: an electrical charge that may be built up on a non-conductive
surface by friction
●● Static electricity serves
Answer: no useful purpose in aviation and cost millions of dollars in
damage every year
●● Voltage
Answer: electric potential energy per unit charge measured in joules per
coulomb
